The tailbone has two very specific purposes. The first, is to fracture when you have a fall that lands you on your butt. This ensures that you will be in excruciating pain, regardless of position you stand or lay, sitting on a donut for weeks, as well as being laughed at for breaking your butt. The second purpose, is to haunt you for the rest of your life. The tailbone has declared that it is now fragile, nee, a delicate little flower, and the slightest misstep will cause it to shift its position just enough to make you howl like you've been run through with an invisible sword. It will make you think that you have broke it again. And again...and again. While there haven't been many studies to date, it is believed, by some, that the tailbone is deeply in cahoots with the pinky toe, also known as the Furniture Finder.

At 7 (in the late 70's before sonars) they took out my appendix just to realise it was extremely healthy and I was still in really bad pain. They sent my appendix home with me in a bottle, I wasn't too impressed. After a x-ray taken they saw I had two huge cysts on my ovary. I can't remember how they treated it only that one nurse was extremely cruel and refused to bring a bed pan and forced me to walk. I can still remember the pain.

I always assumed butt hair was to help with friction reduction, scent dispersal and ventilation when sweating, passing gas and pooping. I've experimented with this theory a few times by after shaving the hair around my anus. Each time, I ended up devloping pimples between my cheeks, chafed badly, had a buildup of sweat between and at the bottom of my cheeks, had issues releasing gas since the scent bubble literally got trapped between my cheeks and had to roll up and out to escape (the popping of which I could feel on my lower back), and finally, I noticed that I produced much smellier, more forceful, and more audible gas. Regrowing my butt hair got rid of all of the above issues.

The answer to butt hair is #3 for chaffing. A process I have done is to shave only 1 side of the area at a given time, which removes excess hair from a single side with zero downsides, if done properly. The next time, (a week or so later), I shave the other side with the same results and keep the hair shorter and more manageable. If both get shaved at the same time there are many problems, mostly related to sweat as the skin cannot breathe. So, only clear one side at a time because you need SOME hair down there to counteract sweating, getting rashes, and chaffing.

I have an extra tooth (if there were more it would look like a third set of teeth) under the middle of my bottom jaw. It isn’t completely formed which means if it ever pushes on the other it will have to be surgically removed from below

Q-tips are actually fine as long as you don't push into the ear canal. I use them to scrape lightly around the edges, putting a little pressure on to the canal as possible. You can still remove a decent amount of superfluous material without pushing it further in. The problem is, your instinct is to just drive it further in and start scraping, and most people don't even know where to stop in the first place. So really, it's better just to tell people don't do it at all. Massaging the space between your ear and your jaw/cheekbones and wiggling your jaw around can help break up a blockage. Holding your breath and blowing or sucking can also help to move material around and eventually drain into the sinuses. A warm moist rag over the ear may also be helpful. You can try using fluids. Warm water or even air can help somewhat, but can be unpleasant, and if you're careless, could be harmful to the ear drum. I've seen mixed opinions on hydrogen peroxide. On one hand, it's excellent at eating ear wax and can absolutely clear a blockage. On the other hand, it's highly corrossive, and will dissolve any biological matter it can. Giving that unfettered access to the inside of your face can be obviously problematic. I've seen first hand where a kid's eye started bleeding moments after recieving H202 through the ear. He turned out fine, but it was definitely a brick-shitting moment.

The appendix is basically an external hard drive and/or a system restart for your intestines. It stores a backup of the essential operating system and any major updates it may have learned. If your (intestinal) system gets wiped, the appendix can attempt to restore it to a previous functioning state.

Loved this video. For butt hair: we as human have (generally) hair around sensitive areas that we need to keep for reproduction, like genitals, or "body holes" that are susceptible/sensitive to environmental harm. For example head hair to avoid damage from sunlight incidence, nostrils hair to retain airborne pathogens and allergens, eyelashes for the same reasons and eye protection, hair in the ear canal or microvilli for protection as well as the same functions as nostrils, etc. Butt hair evolutionarily may have emerged for preventing small insects and other little animals to get into our body (as we were not wearing clothes/underwear thousands of years ago). Many insects and small coprophages are attracted to 💩 and humidity, so the hair can get them entangled and prevent them to keep going in ;)

I was always confused and horrified when I would see someone clean their ears and have a big old chunk of brown stuff come out. My ear wax is almost entirely clear most of the time and not much more viscous than water. Led to a lot of ear infections when I was a kid cuz it's not really doing much except for irritating me until I shake it out like swimmer's ear 😅

Fun fact: Wisdom teeth are normally not pulled in a lot of countries. A dentist will pick a rear molar that's the most worn and pull those teeth instead. That allows the wisdom teeth to naturally come forward and the patient has new rear molars :) and the process is way less painful compared to getting impacted wisdom teeth cut out of your jaw. Unless the wisdom teeth are so impacted that they are cracked, there's really no reason to get them pulled. I had to threaten to report a US dentist to get him to pull 2 rear molars with failing fillings instead of cutting wisdom teeth out of my jaw. Those wisdom teeth came in beautifully after about a year.

I would guess that butt crack hair as well as axilla hair also help suppress the creation of anaerobic environments in body folds by allowing air in between the strands of hair. Anyone who has ever worked around inactive and morbidly obese people can tell you just how much fun those folds can be when they cook long enough without any air circulation.

It had caused me so much pain, that even moving my body from left to right while laying on bed was so painful. I wasn't able to walk too since the pain was so much. I felt hard like a rock. Though when I reached the hospital, I had to use a wheelchair. That is someone pushing me of course. But after that, the surgeons called for an Emergency operation and was saved and still saved from what could have been my death.

On the subject of wisdom teeth and jaw size: I have always speculated that the my family’s larger jaw size may have something to do with our diet. I grew up on a cattle ranch in Montana in the Eighties and Nineties, and let me tell you there were some lean years. We grew our own vegetables and ate the cattle that were too injured to save. There were some REALLY good steaks, and also some incredibly tough ones. The veggies were sometimes terrific, sometimes stunted and woody. I recall a number of times that I paused eating, not because I wasn’t hungry , but because my jaw was too tired to continue chewing. Our family dentist insisted on pulling my lower wisdom teeth as soon as they crowned around age 19. (Like my father, I never developed upper wisdom teeth or adult eye teeth). Now, I occasionally cut up my lower gums because of the lack of matching molars. I have to chew with an underbite to match molars in the back of my mouth. On a side note, I still resent my dentist for insisting on pulling my oversized baby eye teeth so he could replace them with virtually identical implants. I have to floss after every meal to remove the food particles that accumulate under the implant caps.

Speaking of butts and chasing down prey to exhaustion, I saw an Australian documentary on feral cats and the Aborigines that decided to make them food. I was impressed by this rather hefty woman chasing a feral cat, then finally walking over to it and just picking the exhausted thing up. This is now how I catch my dogs when they're avoiding their bath.

When I was 14 I had my tonsils removed due to a investigation why I had an immune response resulting in a "cold" inflammation in my joints. I had in that time mild throat inflammation in my throat and they've said my tonsils must go because they might be the underlying cause of the whole thing. Years later they have discovered I have an autoimmune disease called Bechterew (aka Ankylosing Spondylitis) doe to a antibody called HLA-B27. Since then I am much more susceptive to viral or bacterial infections because my first line of defence in my throat has been removed. Removing the tonsils is still a very common practice where I am from (Hungary). I am worried that many more young people will suffer the consequences in later life without knowing how vital this organ is or was to them. I am now 44 and need to keep a close eye on what I eat or think twice if I washed my hands before taking any food because the very next thing I notice is having a diarrhoea or runny nose. My defence has been compromised by well educated doctors believing this organ can be removed without a price to pay.

On butt hair: As someone who once shaved my butt hair, I have experience as to the differences between having and not having it. One reason is that it prevents small chunks from getting too far if you fart. The other, and the main reason I stopped shaving, is that the hair traps sweat. If you don't have it the sweat runs down your legs which is super gross and annoying. It's also a pain if you don't keep it shaved due to chafing. The reason I started shaving it was curiosity and I noticed it did make it far easier to clean after pooping.

I had a pilonidal cyst while I was in the army, being a typical soldier I didn’t want to go to sick call, be told it was nothing, and then be accused of “shamming” when I got back to the unit with a “return to duty” sick slip. But it was a bump right at the top of my butt crack, a little to the right, and it *ITCHED* when I had to sit for long times (driving in convoys, classes, etc.) I’d press on it and a watery pinkish fluid would come out, though when it itched it was more opaque and yellowish. It never once hurt. Anyway, this went on for a year or 2, until one night we were on the way back from the rifle range and I was sitting on the wooden troop seat in a 2 1/2 ton truck. My cyst itched like never before, and it was pure murder having to sit around cleaning weapons, turn them in, and wait for everyone to get done. Finally everything was clean, we had formation, and were released. I went right to my room to take a shower before bed, but first I started pressing and poking at the cyst. Foot on the toilet seat, bent forward, standing straight, leaning to one side or the other, trying every position I could think of to press from a different angle. All of a sudden I felt a POP, a flow, and sweet relief. In my hand was what I assume was a mix of hair, blood, dead skin cells, sebum, dirt, etc. It was a couple inches long and actually looked a little like an earthworm. This was about 25 years ago and it’s never come back. I still have a dimple where it was, though. Watching Dr. Pimple Popper has told me the sac was still in there but it’s never grown back.

I was really lucky to have naturally straight teeth. All my highschool friends had to get braces, and some people didn't believe me when I told then I never had braces myself. But, y'know, I'm one of the many people who needed to have their wisdom teeth removed. Something seemingly went wrong during the healing process and it had my gums recede in the far bottom left corner of my mouth, which exposed a hole below my last molar. I had my wisdom teeth removed in 2008 at age 18 - I had to get several fillings on that molar because of food getting stuck in that exposed gap, until I had to get root canal surgery. Worst dental experience EVER. But it didn't end there. The pain persisted because root canal surgery doesn't actually kill sensation to the tooth. In 2016, the tooth broke while I was eating (eating RICE, of all things). I had to go and get it repaired, which was expensive, and they put a crown on it. Lost the crown. Tooth broke again. They put another crown. It didn't help. By 2020 or something, I had had enough. I went to the dentist and told them to pull the tooh. They still tried to convince me to get another crown, but I knew they just wanted my money, so I put my foot down and said NO. Pull the goddamn tooth. From getting my wisdom teeth removed at age 18, I'm now 32 and have 31 teeth. The pain is gone and the rest of my teeth have fortunately shown no sign of shifting. tl;dr Teeth are frickin' weird but please take care of them, and make sure to find reputable and trustworthy dental professionals.

Obviously, your butt cheeks slide back and forth and even high-five each other your whole life. Hair in this region helps immensely with reducing friction to minimize pain, discomfort and potential abrasions to the skin which could allow bad bacteria to infest as well as increasing random air flow between the two.

I go into far too much detail when explaining it to others, but I find that it is half the fun. The conversations even took some interesting turns. Favor be with you, my fellow lover of knowledge. 🖤

If you keep a good track of what your ear wax is doing and you insert the q tip without pushing Then you can gently twist it around and scrape off ear wax around it and then pull it out without ever pushing it back in. that's not impossible to do. It's not only messy, but it will get on anything that you use around your ears, like headphones.

I can just imagine the ancient, pre modern man pick up lines: "damn girl! You hunt with that ass?!" 😆

I've once shaved my Butt Hair and I can vouch for reason no.3. It does help to reduce friction and rashes when you walk, especially in summer when you sweat a lot. NEVER EVER GONNA SHAVE MY BUTT HAIR. THEY ARE PRECIOUS

How do you know the shaving not cause the issue

Butts also help protect and support the pelvic bone when sitting. As someone with an extremely flat but I actually experience pain when sitting in chairs that don’t provide support for any amount of time. It’s a real problem for me.

Maybe because horses are involved in shows? They get inspected and poked and prodded when being judged, so that's just a thought. That said, I sure as hell wouldn't want to be the one putting them on. Because you know that whomever is the last person that horse sees before anesthesia is going to be the first person he'll try to stomp the crap out of when he wakes up!!!

I owned a rat with a crooked tooth, he needed it shaved down every few months. You would think an animal with only four teeth would be less prone to mistakes.

@@bedtimeat8 Are you implying rats only have 4 teeth? Because they definitely have more than that. Each side of each jaw has 3 molars as well, so 12 total molars, plus 4 incisors =16 teeth. We just don't see their molars because they're so far back in the mouth, and they lack canines or premolars.

My favourite vestigial structure is not in humans, but in snakes! My pet ball python still has vestigial legs, and I think that's so cool!

"You're a really good actor absolutely love old-school Hanks narration 👌❤️ also personally got wisdom teeth, but I also got hella lucky, as they sitting vertically inside my lower jawbone & skull. They're not going anywhere. Although, since I'm missing 4 of my adult teeth (thanks Klinefelters), I could probably use them.

Just a detail i wanna clarify here (Because creationists love to misrepresent it) Vestigial means that a structure has lost its original purpose. It does not, however, mean that the structure is useless. Things like the appendix fulfill a purpose, just no longer their original ones.

And in some cases, we're not entirely sure what function vestigial traits perform. Although the current function of some vestigial traits is not exactly vital, such as with the appendix. Then there are other traits that still perform their original function, but also serve another purpose in modern humans.

@@paulplatt2622 See, this is exactly the difference between science and faith. Scientists look at the world around them and draw their conclusions from there, even if they don't like the results. Creationists have a set world view from an ancient book full of inaccuracies, fallacies, and contradictions, and pick the evidence that supports their thesis. And whenever they find something they cannot refute with that method, they chuck it up to essentially magic, either by just saying "God did it" or by saying "God works in mysterious ways", whichever one happens to fit better.

Hi everyone, concerning the "Butt Hair", from my own experience, after having undergone several chemotherapy treatments and like most of the people who have experienced this, I lost all the hair on my body...when I started to walk again and before all the hair grew everywhere, I had irritations in the parts that are not exposed to the sun and where the skin rubbed agains skin (I needed to use some medical cream)... so in my opinion: theory nb.3 is the right answer

I've learned so much from Hank Green and crew over the years. I'd proffer one small correction: nic·ti·tat·ing membrane instead of nic·tat·ing.

About the earwax problem: I have used the "q-tip" method my whole life and never had a problem with it. My mother and wife OTOH used the flushing bladder with liquid or went to the doctor to fix thr problem. Both of these methods ended in fiasco, with the situation worse. Of course eventually it was (sometimes partly) fixed, but not without pain and time. As I said I have never had a problem, maybe a clogged ear 2 - 3 times in my life. Now I don't do this often maybe one time a week or more often less than that. Btw, I never push the earwax IN, I position the tip max in without touching the sides of the earcanal and then "scrape" the sides of the canal in a spiral movement out.

Equally informative and entertaining. Nice balance.
