00:00Walking on a pool tarp is really looking for trouble.
00:04Although they may seem tempting, bright and harmless,
00:08some models are not designed to support the weight of a human.
00:12If you fall through, you will find yourself in a dangerous situation.
00:16First, you will probably have trouble locating the place you fell through.
00:20And once trapped, escaping becomes a matter of course.
00:24These tarps are made to float, so they will stick to your skin.
00:28This debate only aggravates things, and increases your chances of getting into more trouble.
00:33From swimming pools to swamps, danger turns into a bubble that seems to be heading straight for you.
00:39Be careful, because this could indicate the presence of an alligator nearby.
00:44During the mating season, male alligators carry out a whole parade to attract females,
00:50even going as far as to walk in the urban areas of Florida.
00:54It usually takes a few weeks for a male to seduce a female,
00:58and, if she likes him, they will start flirting together.
01:02Nevertheless, the act of reproduction itself is surprisingly discreet,
01:06since it takes place underwater.
01:08All that can be seen from the coupling are the bubbles that rise to the surface of the swamp.
01:14The next underwater threat is much smaller, and measures about 35 cm long.
01:20Glycerine worms may seem insignificant, but they are dangerous little mutants.
01:26During their life, which lasts about 5 years,
01:29they feed on the metal present in the sediments of the seabed.
01:33This metal merges with their jaws, creating a metallic dentition.
01:38Indeed, their ultra-sharp teeth contain 10% copper,
01:42the highest concentration ever found in an animal.
01:46When this red-red worm is ready to attack,
01:49it returns to its digestive system, including its metallic teeth,
01:53and projects its entrails like a torpedo directly on its target.
01:57In addition, its venom contains 32 different types of toxins,
02:01completely paralyzing its prey.
02:03The next threat on our list is a bird, the Pitohui Bicolor.
02:08Behind its mundane appearance, this bird hides a toxic personality.
02:12Its feathers contain a chemical substance called batrachotoxin,
02:16also found in some venomous frogs and some coleopteres.
02:21Basically, when this toxin enters your body,
02:25it disrupts the functioning of the sodium channels in the nervous cells,
02:29keeping them open longer and causing uncontrollable nervous outbursts.
02:34This can lead to paralysis, respiratory problems, or even worse.
02:39So, if you ever find yourself in New Guinea, which is their homeland,
02:44opt for a chicken dinner and avoid this dreadful bird.
02:48Another food to avoid at all costs is globefish,
02:52and a very popular variety in Japan in particular, known as Fugu.
02:56If you absolutely want to taste it,
02:59know that only qualified and certified chefs can prepare it.
03:02Fugu must be handled with extreme caution,
03:05because some parts of the fish contain a deadly toxin called tetrodotoxin.
03:10To understand how dangerous this substance is,
03:13know that every year, about 50 people die after consuming this fish.
03:18Hundreds more show symptoms such as dizziness and vomiting.
03:23If the globefish is properly prepared, and we insist on the sea,
03:27it can be tasted in sashimi or ragout.
03:30But I would not dare to venture into it.
03:33If you ever come across a moldy watermelon,
03:36make yourself useful and do not eat it.
03:39The mold, coming out of the cracks in the peel,
03:42occurs because it was grown in very hot weather.
03:45In the United States, for example, this fruit mainly comes from Florida,
03:49Arizona, California, Delaware, and Texas.
03:52When the watermelons grow in this heat, they begin to ferment.
03:57Once this process is triggered, it creates an ideal environment
04:01for the proliferation of toxic pathogens.
04:04And believe us, this is not a flavor you want to discover
04:07because it can make you very sick.
04:09In addition, if the fermentation process intensifies,
04:12and you cut the watermelon, prepare for the explosion of the fruit.
04:16Get rid of the smelly potatoes as soon as possible.
04:20When these tubers become soft,
04:23they begin to emit a harmful gas called solanine.
04:26Inhaling a sufficient amount of this gas can cause dizziness,
04:30intense hallucinations, and a severe fever.
04:33Usually, potatoes at this stage have a green color.
04:37Although the chlorophyll present on the green skin of potatoes is not toxic,
04:41its presence betrays a concentration of solanine.
04:45This toxin is produced in the green parts of the potato,
04:49the leaves, the stem, and all the green spots on its skin.
04:53This phenomenon occurs because it is the plant's defense mechanism
04:57against insects, diseases, predators,
05:00and, apparently, against humans as well.
05:03To avoid any risk, store your potatoes in a cool and dark place
05:07and remove the skin before consuming them.
05:10The next on our list is a food that we are many to love.
05:14The hot dogs.
05:16Apart from their null nutritional value and their controversial ingredients,
05:20the shape of the hot dogs is perfectly adapted to the obstruction of the respiratory tracts.
05:25It is even the first cause of suffocation in under-14-year-olds.
05:30As an adult, you are probably quite careful,
05:33but it is always wise to avoid hot dog eaters' competitions.
05:37Never pick cashew nuts directly from the trees.
05:40In their natural state, these small seeds contain an oily resin called urushiol.
05:46If you come in contact with this substance,
05:49you risk developing a skin irritation similar to that caused by climbing sumac.
05:54Fortunately, the raw cashew nuts that you find in supermarkets are not really raw.
06:00They have been roasted at high temperature once or twice
06:04to remove any traces of urushiol, making them safe to consume.
06:08Once rid of this toxin, they go through quality control before being sprayed.
06:14One thing that is not so safe to buy, on the other hand,
06:17are the clothes labeled as resistant to stains.
06:20It seems like a good deal, but these articles can contain perfluoroalkylated and polyfluoroalkylated substances,
06:27which are known to disturb the body.
06:30In addition to the usual treatments and dyes,
06:33these fabrics receive an additional dose of chemical products,
06:37which remain present even after several washes.
06:40Clothes resistant to stains could thus be toxic and cause various health problems,
06:47such as skin eruptions, headaches and cognitive disorders.
06:51Another warning too often heard but that it is important to repeat,
06:55never stand too close to a moving train.
06:58Why?
06:59When a train passes quickly, air flows at different speeds on each side of you.
07:03According to Bernoulli's theorem, the air pressure between you and the train is lower than that on the other side,
07:09creating a kind of suction that can pull you towards the train and put you in danger.
07:14It is therefore always advisable to stay away from the tracks to prevent any risk of injury.
07:19But if your travel plan involves getting on the passenger seat of a car,
07:23avoid putting your feet on the dashboard.
07:26I understand, we have all done it, but this relaxed attitude presents serious risks.
07:32One of the main reasons to avoid putting your feet on the dashboard
07:36is the danger it represents in the event of an airbag deployment.
07:40These inflatable cushions are designed to deploy with considerable force in the event of an accident.
07:46If your feet are in the air, you are much more likely to suffer serious injuries
07:50such as fractures or dislocations when the airbag is deployed.
07:54In addition, this bad habit compromises the effectiveness of the seat belt.
07:59With your feet in an elevated position, the seat belt could not hold you firmly in place.
08:05Imagine now that you are hiking.
08:08You are walking in the forest, looking for the perfect place to set up your tent.
08:13But wait, is there an orange cross painted on this tree?
08:17You might think it's just a sign indicating that the tree is going to be cut down,
08:21but in reality, it's something else.
08:24The US Forest Service uses this symbol to mark the limits of the lands belonging to the government.
08:31So, if you see an orange X on a tree,
08:34the best thing to do is turn your heels and come back on your feet.
