FunTranscript
00:00You have to walk a few kilometers with an incarnated nail.
00:04Yes, but think of people who are attacking extreme races and marathons.
00:08To give the best of themselves, they need first-class training and solid shoes.
00:13But there is one more thing. Perfectly cut foot nails.
00:17And believe me, keeping your nails in good condition is quite an art.
00:21There are many rules on how to do it correctly.
00:24To avoid nail problems, some athletes choose to have them removed,
00:28which allows them to avoid a whole bunch of problems.
00:31Take the example of Charlotte Vazarelli, an ultra-race champion
00:34who had to say goodbye to two of her toenails because incessant pain affected her performance.
00:40The intervention lasts about 45 minutes.
00:43A podiatrist insensitizes the toe, applies a garrote and carefully removes the nail to the root.
00:49He then uses carbolic acid to prevent the nail from growing back.
00:53The recovery is quite fast, but sometimes you have to do it two or three times
00:58to make sure that the nail has completely disappeared.
01:00Let's suppose now that you have accidentally lost your toe nail.
01:05As you are not a professional athlete, you want to help him grow back.
01:09Well, it will take you up to a year and a half to fully recover.
01:12Foot nails grow three times slower than hand nails,
01:16because of about 1.6 mm per month.
01:19In addition, the older we get, the slower the process is.
01:22With age, these nails thicken and round, which slows down their growth.
01:27Not everyone suffers from smelly feet.
01:30But if it happens to some people, it is for a specific reason.
01:34Our feet have about 250,000 sudoriparous glands.
01:38For comparison, our armpits have 10 times less, or about 25,000.
01:43However, it is not the sweat that makes the feet smelly.
01:47It is the bacteria that are responsible for the bad smell.
01:51The main reason is often the lack of ventilation
01:54and the fungi that develop in humid environments.
01:57For example, if you have muddy feet.
02:00Feet and feet are part of the daily life of humans.
02:03When we eat, our intestines are not able to digest all the food perfectly.
02:07Gases are a by-product of the digestion process
02:10during which bacteria decompose the remains of food.
02:13And all these gases must eventually escape.
02:16This means that, on average, we emit between 12 and 25 pees a day.
02:21But do not worry.
02:23Gas retention will not cause you serious problems.
02:26Of course, this can cause some abdominal pain,
02:29but being polite during dinner will not have serious consequences on your health.
02:35As disgusting as it may seem,
02:37the smell tells us that our body is doing its job.
02:40This sticky substance, whether it is white, yellow, green or even brown,
02:44is nothing more than an accumulation of white blood cells fighting an infection.
02:48This means that your immune system is working properly.
02:52Of course, if you see pus after a major surgical intervention,
02:56you should consult your doctor.
02:58But for small injuries, even pus,
03:01it is to know that your body is healing, even if it is disgusting.
03:04You can call it the precious sugar of white blood cells, if you prefer.
03:08Can you pinch yourself without feeling anything at all?
03:11Go ahead, grab a little skin on your elbow and pinch it hard.
03:14Surprisingly, the feeling is not as unpleasant as that.
03:18It is because the nerve endings vary from one place to another of your skin.
03:22The skin of your elbow is a kind of superhero.
03:26It is very resistant and has few pain receptors.
03:30However, some delicate areas of your body are full of nerve endings,
03:37which makes them hypersensitive and often makes you scream
03:40when you accidentally hit yourself against something.
03:43You can eat anything without feeling the taste of it.
03:46All you have to do is pinch your nose and take a big mouthful of maize,
03:50so unappetizing that we have just served you.
03:53Try it one day, it's magic.
03:55The fact is that our taste buds can only detect five flavors.
04:00Sweet, sour, bitter, salty and umami.
04:05This flavor is found in different types of meat.
04:08However, it is not the tongue, but the smell that really gives life to all these flavors.
04:14If you plug your nose, you eliminate the aroma
04:17and let your brain rely only on these little butterflies.
04:21It's a good tip when you have to eat something you don't like,
04:25but which is polite.
04:28If you are asleep and someone blows a breath of air into your eyes,
04:32they won't move an inch.
04:34But if you are awake, they will start to flutter like crazy.
04:38So, the next time you want to check if someone is really sleeping or not,
04:42try this little trick.
04:44You have probably noticed that one of your nostrils
04:46is always more crowded than the other when you are snoring.
04:49But that's perfectly normal.
04:51It is not uncommon for one of them to double activate
04:54so that the other takes a little rest.
04:56And they alternate throughout the day.
04:58This is called the nasal cycle.
05:01In general, a nostril provides about 75% of the breath for a few hours
05:07before the other takes over.
05:09As this cycle is controlled by the nervous system of your body,
05:13you can improve this natural process
05:15by consciously changing nostrils every time you breathe,
05:18which will help you relax.
05:20It may seem a little ridiculous at first,
05:22but it's a fun trick to try on your child when he needs to calm down.
05:28The bones of your feet represent about 25% of your skeleton.
05:32We have 206 bones in total,
05:34and each of our feet has 26 bones,
05:37which makes 52 bones in total for your two feet.
05:40If you do the math, it represents about 25.24% of the total.
05:46Genetically, human beings are identical to 99.9%.
05:51But not all of our genes are really human.
05:54Of the few 20,000 genes in our DNA,
05:57about 8% come from ancient viruses.
06:00In addition, 40% are made up of repetitive sequences
06:03that scientists also suspect to be viral.
06:07These viral genes have the ability to move and replicate,
06:11which could be linked to certain health problems.
06:14In short, you are only half human
06:16in terms of your genetic heritage.
06:18Believe it or not, it's rare,
06:20but it happens that teeth grow in some people's ovaries.
06:23These strange growths are called teratomes,
06:26and they can contain all kinds of things,
06:28such as pilate follicles, skin, muscles, and many other things.
06:34The largest ever discovered teratome
06:36measured 45 by 25 centimeters,
06:39and it was taken on a 74-year-old woman.
06:42As the brain does not have a pain receptor,
06:44doctors can perform surgical interventions
06:47without the patient falling asleep.
06:49Sometimes they can even argue.
06:51No, it doesn't come straight out of a horror movie.
06:54The fact that patients wake up during surgery
06:56allows surgeons to avoid any serious injury.
06:59It's still a little weird, isn't it?
07:01Surprise!
07:02Your brain is the fattest organ in your body.
07:05It contains about 60% fat,
07:08and that's a good thing.
07:10These fatty acids are essential for the proper functioning of this organ.
07:14An imbalance can expose you to many health problems.
07:18But when you have children,
07:20your well-fat brain becomes smaller,
07:22as if it were on a diet.
07:24We have seen in mothers and fathers
07:26a shrinkage of the areas linked to social information
07:29and decision-making.
07:31These changes are perfectly normal
07:33and facilitate the education of children.
07:35However, whether you have children or not,
07:38your brain capacity
07:40does not stop decreasing from the age of 24.
07:43Some studies show that your cognitive speed
07:45begins to decrease at this age,
07:48and that you lose about 15% of this speed every 15 years.
07:51Therefore,
07:53when the quarantine approaches,
07:55don't be surprised if your brain takes a little longer
07:57to process information.
07:59Your ring can betray your civil status,
08:02but it contains some other interesting secrets
08:04that have nothing to do with marriage.
08:07In 1998,
08:09evolutionist biologist John Manning
08:11discovered that if your ring is long,
08:14it can mean that you had a very high prenatal testosterone rate.
08:17Since then,
08:19several studies have confirmed this hypothesis,
08:21showing that people with a ring longer than average
08:24tend to excel in sports.
08:26If you look at your hands
08:28and you notice that your fingers are really very long,
08:30don't draw conclusions too quickly.
08:32The subject is still in debate among scientists.
08:35However,
08:36it is proven that men whose rings are longer
08:39are more prone to anger than others.
08:42Maybe that's why boxing gloves look like mufflers.
08:45You have to guess who the real champion is.
