I have written before on the importance of education on things we normally consider basic, such as personal hygiene. This article is my attempt to work towards that ideal, providing some of my experiences with everyday personal care and habits, which will hopefully be helpful for the younger readers of this site.

Dental care

There is a hugely damaging habit accepted in society, of eating dessert last. This is damaging because sugar molecules and their derivatives tend to be highly adherent and provide nutrition to bacteria in the mouth, thus finishing a meal with dessert means there will be ample time after the meal for the bacteria to eat the sugar and multiply. This includes sugary drinks and juices served along with the meal. I use a reverse approach, starting a meal with the dessert, then having the main savory course, and finishing with a salad. Except for rare occasions, I only drink water, and avoid sugary drinks and juices. The best way to clean teeth and mouth surfaces is not with a brush, but by chewing vegetables and fruits, whose spongy and fibrous texture acts as a "chewable toothbrush". Finishing every meal with a salad (a plain salad, without a sugary and oily dressing) leaves the mouth in a state that will reduce bacterial growth in the interval after the meal.

Finishing a meal with fruit is also an option, but less preferred because fruits have a higher sugar content and tend to be acidic. After eating fruits, I recommend doing at least three full mouth rinses with water, to remove most of the acidity, and for particularly acidic or bitter fruits, do a rinse with water and baking soda to neutralize the acid. I keep a container of baking soda for this purpose, to mix in whenever needed. If there are situations where it is not feasible to follow this regime, such as at a social gathering where it is expected that everyone eats dessert last, it is important to excuse yourself immediately after the meal and brush your teeth to remove at least some of the adhered sugar, though over the years I've come to care less about following harmful social protocols so I often skip dessert altogether in these situations.

There are three other habits which help maintain healthy teeth. First, avoid rapid shifts in temperature (hot to cold, or cold to hot, and around water freezing point) - teeth are a sort of natural ceramic and like all ceramics they form cracks when stressed from uneven thermal expansion. After eating ice cream, wait a few minutes for teeth to slowly return to body temperature before drinking hot tea. Second, if drinking sugary drinks (soda, juice, sweet tea) use a straw to direct the sugary liquid onto the tongue so it does not touch any teeth. This prevents sugar from adhering to the teeth and supporting bacterial growth there, and also prevents thermal shifts in tooth temperature as the cold or hot liquid does not touch the teeth. Third, avoid consuming staining foods / drinks like wine, coffee, and tea, as well as cigarette smoking, as all these will over time stain the teeth and make them look less clean. If you do consume these, follow up with a thorough fresh water rinse soon afterwards to help remove the staining material (I do not recommend brushing soon after eating because acids from the food may leave the enamel softened for a while and brushing at that time can cause damage to it more easily).

When I am able to end all meals with vegetables or fruits, I haven't found a need to brush more than once a day, in the evening before going to bed (so that the time spent in bed, which is free time for bacteria to eat and multiply, is minimally damaging since there will be little nutrition left for the bacteria). It is important to add to this procedure an antiseptic mouthwash gargle (I like the Listerine brand, and have been using the purple colored one with alcohol), as well as flossing. For the order, I start by flossing, then brushing, then the mouthwash. When flossing, use a long string of floss (about 50 cm) and slowly cycle through the whole length, such that each space between teeth gets a new section of the string, which avoids cross-contaminating bacteria from the spaces between teeth and provides a more effective dry textured surface of the floss to remove adhered particles. I really don't like the small plastic-handled flosser devices for this reason, since that tiny length of floss should only be used for one or two spots and not whole mouth. With the floss, apply tension such that one then the other surface of adjacent teeth has the string sliding across it with friction, as this is what will displace adhered matter. I use the large 240 yd container of Reach waxed floss, so I never worry about using too much floss in a day. The Reach brand has been what I've returned to after trying others, due to its grippy texture (this helps trap and remove particles) and its tear resistance (this helps exit tight spaces between teeth without tearing the floss and leaving tiny uncomfortable bits of floss between teeth - probably my least favorite experience in flossing).

When brushing, replace the toothbrush every few months, use only slight pressure (the brush should not look like it's been chewed through - the bristles should remain straight facing upwards throughout its life, if they become bent sideways you're using too much pressure - remember the cleaning action is at the bristle tips not bristle body), and make sure to reach all tooth surfaces with a circular motion which will take about 2 minutes in total (use a timer to make sure - this might feel longer than it seems). I use the Philips Sonicare toothbrush, and highly recommend it, because its high frequency vibrations (some kHz) effectively remove adhered contaminants - much more effective than hand brushing or "cheap" low frequency electric brushes. I also use the Hand&Hammer toothpaste with baking soda, because the baking soda provides an acid neutralizing advantage as well as a light scrubbing action. I avoid using whitening products, and also avoid consuming staining foods like coffee, tea, coca-cola, cranberry juice, and wine; my teeth are not bright white but I don't really care about that as long as they are healthy.

It is also important, and much under-appreciated, to brush your tongue. The tongue is a textured surface with high surface area, where bacteria and nutrients can hide out and provide a source of chemicals harmful to the teeth even after you have cleaned all tooth surfaces. Use the toothbrush, with light pressure, to brush along the full length of the tongue, and rinse with fresh water, then repeat this a few more times to ensure most particles have been displaced. Make sure the toothbrush completely dries out after each use. When rinsing with mouthwash, swish it in the mouth vigorously to cover every surface including between teeth and roof of mouth, and also gargle with head tilted back to reach the back of the tongue which cannot be easily brushed (but still capable of holding substantial adhered matter which provides nutrition for bacteria and often leading to tonsil stone formation). The recommended time for the Listerine mouthwash is 60 seconds, which is a lot longer than most people seem to do (they just swish it around once and spit out), but this long time is essential for the antiseptic effect to work.


Wet sponges are like a germ hotel. If you want to minimize germs in the kitchen and bathroom, the biggest step to take is proper management of sponges, mops, rags, and towels. Ensure that sponges dry thoroughly after each use, and as the last step of the washing process saturate the sponge with soap solution so that the wet environment inside the sponge is not amenable to germs. Similarly towels should be always hung up to dry, exposing maximum surface area to the air, so that they can remain hygienic. If there is any trace of a moldy smell coming from the towels or sponges, throw them out and get new ones, and dry the new ones better.

Cooking is not all that difficult, and in case no one bothered to teach you, it doesn't take much work to learn by yourself. Cooking is basically carrying out a very simple chemical reaction: raw ingredient + heat + time = cooked ingredient. So once you have your ingredients, the only two things to worry about are the heat and the time to apply the heat for. An important skill is patience and just letting the heat do the work; when I was starting out I felt the need to constantly check everything and was always getting undercooked food, then one day I was busy and distracted, and barely attended to the cooking, and the result was great. The reason recipes call for boiling water is that this is an easy way to tell the water is around 100 C (less with elevation), however there is no requirement for this precise temperature: you can cook with much higher energy efficiency by keeping the water at 90 C (where you won't be losing as much energy making steam that doesn't do anything), or you can cook much faster by having the water above 100 C in a pressure cooker. On efficiency and convenience, it is difficult to beat the microwave - it delivers energy directly to the food so is much more efficient (meaning also faster) than other methods. The microwave is often seen as only relevant for heavily processed foods like hot pockets and frozen dinners, however it is perfectly usable for "real" cooking like vegetables, rice, beans, and sauces (avoid microwaving full eggs as they can blow up and make a big mess). Pasta should be placed in water that is already hot, so that it forms a firm layer on the outside that keeps the pasta shape and texture; if placed in cold water (or stored in a high humidity location) the pasta will be soggy. Rice, beans, and grains on the other hand should be placed in cold water to maximize the time for water to permeate into the grain to give a more palatable result. Still, the difference between the two approaches is not anything dramatic, the food will still be edible if cooked for long enough even if it's not gourmet level. Vegetables are best served steamed (vastly better appearance and flavor than boiled) because steaming does not leach the nutrients and flavors, and maintains a vibrant color - you can buy a steamer type pot to do this conveniently. Eggs are easy to make by boiling or by frying, and even if you undercook them, they're not too dangerous to consume, so they are a good animal product to practice cooking with. With meat you should take a lot more care because all contaminated surfaces should be cleaned, and the inside temperature should be measured (use a cooking thermometer for this). I largely avoid meats because of moral and practical concerns, as well as the sketchiness of the meat industry (adding colors to make sick anemic meat look more healthy, washing diseased carcasses in bleach to get rid of the stench before cutting the meat for sale, animal abuse).


One thing must be remembered above all: losing weight is done primarily in the kitchen. There is a belief popularized in western society that to lose weight one has to go to the gym and become sweaty and miserable from all the hard physical work. This is not so. All it takes is reducing caloric intake and re-balancing other consumed nutrients. Because I am going against deeply ingrained beliefs, let me repeat: if you want to lose weight, the way to do this is by controlling what you eat (and drink - especially the sugary sodas). Forget about gym and exercise, and focus all your efforts on tracking and systematically improving your food (and soda) intake, and results will inevitably follow. The fact is, this mental effort of facing a dependence on food, that is to say an eating disorder, is significantly more difficult and unpleasant than going to the gym and lifting some weights, and this is why so many people try to follow the relatively easy solution, get discouraged and annoyed with exercise, then return to their old comfortable habits. If you intend to use exercise to aid weight loss, once you have established a healthy caloric intake through your diet, the aerobic long-lasting type of physical effort, like walking, bicycling, hiking, and swimming, will tend to burn more calories than lifting weights. Also there is a significant use of calories for maintaining body heat - so wear lighter clothing all the time to burn more calories.

I recommend always drinking lots of water. If nothing else, think of the risk of kidney stones forming as a reason to stay well hydrated. A gauge on this is the color of urine - it should be a faint yellow color, with little odor. If it is fully transparent you're over hydrated, which is preferred to the case when urine is a rich dark yellow which means you're under hydrated. There are other benefits to being hydrated - water helps maintain body temperature, improve blood circulation (viscosity impact) and brain function, and it helps with immune function. When I feel ill, I increase my water intake along with food intake, because when the immune system fights intruders the harmful chemicals (dead and decomposed cells) are removed in urine and feces, and with a higher water consumption I increase the rate of these processes thus reducing the harmful chemical concentration within my body.


I try to avoid taking any prescription medications. The only supplements I take are vitamins and minerals, where I take a "once a day" vitamin pill, and an increased dose of Vitamin D, Zinc, and Magnesium. Though I will say with a healthy diet, the effects of these supplements, if any, are subtle. Vitamin D helps immune system function especially with low sunlight - in the paraphrased words of a doctor (whose name I can't remember), "Nothing about the flu itself makes it seasonal. There is no flu season, but there is low vitamin D season.". Zinc is another supplement that has been linked with better immune performance. Magnesium helps me with overall energy. I believe medicines are overprescribed and overbought in the US and some other countries. There can be a dangerous feedback loop of medications causing side effects, for which new medications are prescribed, leading to new side effects and more medications, and so on. To avoid this, it is important to always critically evaluate any medications you are regularly taking and test whether they are actually contributing to your welfare. I find no use for tablets like Tylenol and Nyquil, even when I feel sick, I prefer just letting my immune system do the work and powering through it rather than burdening my liver with additional chemicals, and I have noticed no impact on the duration of colds from taking such pills. What does seem to reduce cold symptoms and severity is drinking lots of hot water (the water aids in excreting undesired substances from the body, while the heat applied at the throat aids in stopping bacterial multiplication), and eating delicious sugary foods (the sugars and fats give energy and nutrients for the immune system to make new cells and fight the invading cells). Fever reducers also don't make much sense to me, except in emergency scenarios, because fever is part of the body's arsenal in using heat to compromise the invading organisms; when I feel particularly ill I find thick blankets and retreat under them, being very hot and uncomfortable, but knowing that the heat is helping my immune system fight back.


There is a significant misconception, that conflates going to the gym, exercising, losing weight, and gaining muscle, perhaps because people want to feel good about doing hard physical work for no reason. I will repeat again: weight loss is done in the kitchen, period. If your goal is to lose weight, going to the gym will only be a distraction (which may be useful to the extent it keeps you away from the kitchen). (Chances are, if you're overweight, you're eating a lot outside the kitchen as well, but the point still stands - it is the eating (and drinking sugary sodas) that is causing the weight, not the absence of gym attendance) If your goal is to gain muscle, the issue is not so clear. I will say that muscle growth is done with nutrition and supplements, but this is not the full story, because the body does react to muscle loads in growing muscles (much as it does with bones). Still the primary impact is part nutrition and part genetic, so start gaining muscles not by going to the gym, but by improving your nutrition, and more importantly by going back in time and editing your genetic code so that your body builds more muscles. Or more simply, inject various growth hormones that will have the same effect. After all, the meat industry has as its sole purpose the production of muscle tissue, and they don't do that by putting animals on treadmills. Milk is produced using cows injected with growth hormones, and these end up in the milk to some extent, so you can begin by drinking lots of milk (and eating lots of meat, from similarly injected animals).

For my part, I did an experiment where for about a year I did anaerobic upper body exercises on an almost daily basis for 6 months, but without substantial dietary changes, and at the end I had some marginal performance improvement but nothing extraordinary. To further prove the point, for the next 6 months I did barely any of these exercises, and afterwards my strength performace was pretty much identical, though the appearance of my muscles was not as good as after the training. Because of my philosophical beliefs, and of more mundane constraints like time and money, I don't feel justified in increasing my consumption of animal products (namely milk, eggs, and meat) for the sake of muscle gain, though if I wanted to have muscle gain, my first step would be to substantially increase my consumption of these items (and you will see this confirmed in any professional athlete's diet - to be sure, this can also be done without animal products, but doing so takes a lot more research, effort, and money). My genetics predispose me to a medium build, and I've come to design my life around being comfortable with that, as changing that would take too much effort away from other more enjoyable pursuits.

Continuing debunking this gym myth, it is important to note that physical exercise and gym are only distantly related. Walking around is perfectly good physical exercise, as is doing manual labor, going skateboarding, playing soccer, churning butter, woodworking, climbing boulders, or having sex. There are many opportunities to use your muscular strength and feel the joy of physical effort, without stepping foot in a gym. In fact I would say the gym is the least fun and interesting way to exert physical effort, a convenient but boring way, an artificial construct that the brain recognizes as such. It is more rewarding (and thus habit forming) when the physical exercise has both a competitive and a social component, so if your goal is to feel good about exerting physical effort, and potentially improving your muscle appearance in the process, then find a sport activity that you enjoy and can progress in, and make it your hobby. Better yet, plan out a career that involves physical activity (that is, a non-sedentary one, which is increasingly hard to find) - this way you will feel rewarded by using your muscles to do actual useful work instead of moving weights around aimlessly for the sake of exercise. But remember, if you don't improve your diet, your gains will be severely limited (both muscle gain and weight loss), because nutrition is key, and ultimately hormones and genetics set the direction and extent of bodily changes.


Shaving face and neck: If using a razor, shaving against the direction of hair growth seems to lead to irritation, while shaving along the direction leads to pulling, so I prefer to cut at a perpendicular angle to the hair direction. I rarely use a razor nowadays, because I don't feel a need for such a close shave and I can avoid skin irritation in this way. If you do use a razor, make sure to apply shaving cream beforehand and a moisturizing protective lotion afterwards. I have taken to using a hair trimmer (with ceramic blades, no less) in place of a manual or electric shaver, for all of my facial hair. My hair is very thick and tough, so it gets stuck in the tiny openings in the shavers leading to clogging and pulling, whereas the trimmer has an open blade surface that easily cuts through thick hair; the trimmer won't achieve smooth skin and will leave a stubble, but the painful pulled hairs and ingrown hairs will be a thing of the past, so this is my go-to method now. Make sure to also periodically shave around the neck and the back of the head, to maintain a tidy look in between haircuts. Also trim your nose hairs and hairs on the outside of the ears (these might not show up until late 20s), and while we're at it, trim your fingernails and toenails as well (using a nail clipper). But don't use the nail clipper for nose hairs - it's difficult to fit up there and you just might get "athlete's foot in your nose" (House MD S3 E12); I use scissors advertised for baby nail trimming - they have short blades with safe curved edges and can be easily maneuvered inside the nostril.

Shaving whole body: I was quite skeptical of the idea at first, especially since in our current culture this is seen as "feminine", but after getting over the mental barrier, it is actually quite nice and helps me feel cleaner. My genetics are fairly hairy, not werewolf level, but it would be close if I just let everything grow out. Doing a body shave about once a month maintains a tidy appearance and makes showers more enjoyable (also no more stray pubic hairs showing up around the house). As with the face, I avoid close shaves because that leads to ingrown hairs and irritation. Two areas of concern are the butt where pressure is applied while sitting causing the hairs to retract slightly, and the underarms where drawing the arms inwards lead to a similar retraction, so I make sure to leave maybe 0.5 mm length hair by trimming a bit away from the skin. I again use an electric trimmer, but not the ceramic blade one as that is too aggressive; my favorite has been the Philips Norelco Bodygroom series which has a blade with rounded points so even if you push it into the skin it won't cut the skin. The cut hairs are a bit sharp so for about 2 days after shaving, you will notice the sharpness when touching your skin, eventually the points get rounded off and this goes away. This sharpness does not lead to skin irritation by itself - the irritation appears if the shave was too close. With practice, doing a full body shave takes about an hour, though it was closer to two hours when just starting out as reaching some areas can be surprisingly tricky. It helps to have bright lights and a few large mirrors to make sure you get even coverage.

Skin care

I had really bad acne in high school. My face was absolutely greasy, red, and painful. The hormonal changes of puberty definitely play a role, as do the impacts of stress level (also hormonal). Another important factor is diet - at that time I was eating largely processed food (the terrible processed food that was the only option available in school, I still get flashbacks of the pizza slices served which could saturate about a dozen napkins with whatever hydrogenated oil the pizza was covered in), and I'm sure this contributed to the acne. Nowadays my skin has mostly returned to normal but I can get acne from time to time - whenever I do, it is always traceable back to an unhealthy meal, and this is not necessarily a calorie-rich meal but rather one that is highly processed and not something I usually eat. My body responds especially poorly to greasy foods, so if I eat a bunch of breakfast sausages or similar greasy items, I may as well set a timer for the acne to flare up. Also I want to note my experience with gluten-free diet: after about two weeks gluten-free, which is surprisingly difficult to do unless you have full control over every meal, I noticed a substantial clearing up of the red areas on my face, so avoiding gluten or at least highly minimizing it is something to consider if you have problems with acne. There is also a fairly conclusive link between stress and various skin conditions including acne and eczema, this is because stress causes changes in metabolism. So, make sure to eat a varied diet (with fruits and vegetables, reduced gluten, and reduced processed (liquid) fat), and try to reduce stress levels as feasible. Still I think even doing that would not have done much for me back in the day when faced against the impact of puberty. For me it didn't make much of a difference as to how often I washed my face - acne formation starts under the skin and is controlled by the skin's production of oils. The usual acne treatments like benzoyl peroxide or salicylic acid did nothing but dry out my skin, and the "you must use it twice every day for 4 weeks before you see any changes" is just an excuse to blame the patient for an ineffective medicine. Prescribed antibiotic pills didn't do anything, and antibiotic cream helped a tiny little bit. The only treatment that did anything of substance was retinoid (Accutane), but it required an oppressive blood test for every prescription so I stopped this after three months when there had been adequate improvement. I was also warned of various severe side effects, but I did not notice these. The beneficial effects of the treatment seem to continue for a few months after discontinuation. At some point after that it seems my hormonal levels slowly mellowed out (over years) so now my skin is decently ok, though patches of redness still remain. I do recommend using a moisturizer, shop around to find one that works well with your skin, I like to use Lubriderm as it feels non-greasy and absorbs well. It may be tempting, especially if your skin produces a lot of oils, to clean off the oil with solvents like alcohol wipes, however this does not help with acne, it just dries out the skin and makes it irritated while potentially allowing more bacteria to enter the underlying skin layers. Instead, wash with soap, dry with a clean towel (the towel helps absorb oils and exfoliate), and apply a moisturizer. There are "non-greasy" moisturizers which feel really dry (the moisturizer mechanism of action is not in wetting the skin, but rather in forming a protective layer on the skin that keeps the skin's natural moisture levels from escaping into the air) which can be a pleasant option if your skin is oily.

Hair care

I cut my hair short, and this makes it quite easy to keep clean. With long hair, you will need to be a lot more selective with what products you use and what routines you develop. Hair has a tubular structure that is permeable to water, so controlling the humidity of the hair is an important step in styling. For example, drying hair rapidly in air leads to a "ruffled" texture, while drying it slowly wrapped in a towel for an hour or so leads to a softer flowing texture. It is also a good idea to use a shampoo and conditioner, with different amounts of water in the shower, and giving additional time for the conditioner to coat the hair. With short hair, none of this is noticeable, so life is a lot simpler. I just use a combination shampoo + conditioner, apply, lather, and rinse. I wash my hair every time I shower, which is every day in the summer and every 2 days in the winter (with long hair it may be more practical to not wash the hair during every shower, but it is still useful to wash the scalp).

Haircuts - I never enjoyed getting a haircut; I am not very social so I don't like the awkward situation of coming up with something to talk about, I don't really know how to explain what style I'm looking for so I get a random result each time, and I don't like spending the rest of the day walking around town covered in small hairs. Thus I've taken to doing haircuts myself, it doesn't look pretty, but I don't really care about looking pretty at this point (and anyway that is a function more of my facial structure than hair), so I just set a trimmer to 0.75 inch length and cut all around, then touch up around the ears and back without the length guard. The trimmer with guards (Wahl Corded Clipper Color Pro) can be purchased for less than a single barber shop visit, and is fairly foolproof, as long as you're not looking for a stylish cut. I do all this in the shower, with mirrors and lights set up so I can see all around the neck area, and then cleaning up is easy and quick.

Clothes and laundry

I collect clothes to do laundry once a week. This gives typically one or two washing machine loads, and it is good practice to load the washing machine lightly so it can move the clothes around during the washing process (loaded too heavily the clothes don't move and there is no washing action). I add detergent while the water is filling, though different washing machines will have different procedures. Fabric softener can optionally be used, I don't really like the texture and smell that results so I don't use this. A fairly recent product is freshening pellets that add some fragrance to the clothes (Downy Fresh Protect), though if you use this, make sure the scent is matched to your detergent. Most clothes can be washed with all colors combined and it won't be a problem. If you need white clothes like for shirts and formal wear, it is a good idea to wash them separately (or do dry cleaning). Drying clothes in a dryer can lead to shrinkage due to the high temperatures. Clothes that require a proper fit should be air-dried instead, and this has an advantage of energy savings as well (the clothes dryer is likely the most power-hungry appliance in your home).

Sexual health

Following puberty there is increased interest in sexual exploration. Sex drives vary between individuals, and are stronger in men than in women (they are also quite different in nature between men and women). There is now increased understanding and acceptance of sexual and romantic orientations, however the fragmentation into discrete groups is a cultural construct - each individual has some set of attractions and trends can be observed (such as homosexual and heterosexual). Very briefly, by the age of 16, if you want to touch and be close to the opposite gender, you're likely heterosexual, if same gender then homosexual, and if not really either, then somewhere between asexual and bisexual. Sex drive is hormonally mediated, and at its height a boy might be able to reach orgasm on the order of 10 times in a day (followed by 1 or 2 days of rest). As age increases, sex drive plateaus, to the point of 1-2 orgasms in a day, and desire for sexual activity about 3 days a week (the other days being sexless). This continues into the 30s and 40s where a man would reach orgasm once or twice a week. There are many scenarios where this level is not possible, for instance with high stress and family commitments, and these scenarios should be avoided for good sexual health.

Any imaginary girls reading this (since this whole website is so autistic only males will have made it this far) should be aware of menstruation (that is, periods of bleeding from the vagina), and the medical practice of gynaecology. During a doctor visit, when the nurses and doctors reach in with the cold speculum, force your way into taking the speculum yourself and putting it in on your terms. Ask them for extra lube if need be. And also if you engage in sex, whether you want to get pregnant or not (nature doesn't care what you want), be aware of the realities of childbirth - often (in the range of 1 in 10) it leaves permanent damage (such as tears from the vagina to the anus, which have to be stitched back) and requires invasive surgeries and hospitalization (such as C-section and anesthetic injection into the spine). Pregnancy and childbirth, especially in humans, is messy and ugly and dangerous, not cute and wonderful and angelic. And that's even before all the complications and life derailment caused by the baby's presence once it is born.

Everybody seems to hate the concept of abstinence, that is, not having sex with another person, but this is really quite a good strategy. This is the only sure way to avoid sexually transmitted diseases and pregnancy, as well as a whole plethora of emotional and mental troubles. It is perfectly viable to maintain sexual health through masturbation. If you do engage in sex, it is important to understand the risks. One is sexually transmitted diseases, and the risk can be reduced by using condoms or certain prophylactic injections. Another is pregnancy, and the risk can be reduced by vasectomy or birth control pill / implant, where if you are a man wanting to control this risk you should seek a vasectomy, and if you are a woman wanting to control this risk you should seek a pill or implant. That is to say, if you are a man, you should not be relying on the woman's birth control to prevent pregnancy. Vasectomy is a very simple surgery that does not change hormonal levels (it is not neutering or sterilization) and should be a first priority if your goal is to have lots of sex with minimal pregnancies. Condoms should not be used for pregnancy prevention because they can have mechanical challenges, and the "pull out method" (where the man tries to pull out prior to ejaculation) is synonymous for "we want a baby". These risks must be understood by any individuals engaging in "penis in vagina" sex - nature has devised this process as the pathway to make babies, so unless you're really good at resisting nature's forces (and nature selects against such individuals), you will get a baby from doing this.


The main part of "intoxicant" is "toxic", that is, poisonous and damaging to health. Alcohol is a very dangerous intoxicant, which makes it all the more surprising that it is perfectly legal and indeed widespread in society. As far as mind-altering substances go, alcohol is a really crude one, which can be seen from the poor rigor of historical fermentation processes. I would wager, if you are reading this (meaning your interests and goals have led you to invest time in reading this article), your life would be better off if you avoid alcohol as much as possible. The impact of peer pressure is substantial - when everyone at the party is drinking a beer, it is hard to say no if you are offered a can. At this point you have to apply the valuation of your own welfare versus your social status and appearance to others. Alcohol just dumbs down the mind and lets out primal drives, it does not educate, it does not enhance your experience, it only makes time pass by faster. Another problem is not in the alcohol itself but in the social interactions it can give rise to - there is an obvious correlation between alcohol intoxication and sexual harrasment / rape, again because the alcohol unleashes the primal drives, so this really should not come as a surprise to anyone.

Tobacco is another legal intoxicant, damaging to health and on a social level. It is an addicting substance. Addictions result from a low level of "rewarding" neurotransmitters - and some brains are more susceptible to this genetically. Chances are, intoxicants like tobacco and alcohol are tried either through peer pressure ("I don't really want to smoke, but my friend dared me to") or due to a sense of desperation ("I feel like nothing matters anymore, I might as well try smoking"). Paradoxically, in some cases avoiding "pleasant" sensations like sweetness and orgasm, can actually increase overall happiness, by a quirk of chemistry (the brain has a mechanism to avoid degenerate actions, which decreases the levels of neurotransmitters after an enjoyable sensation - this is why addicting drugs cause a tolerance instead of working continuously at low dose).
