Did you know that some stuff we learned in school isn't exactly on point? Like, remember when they told us you could drink water from a cactus in a survival situation? Turns out, that's more of a Hollywood thing than reality - most cacti have toxic fluids that can make you sick. And what about Pluto being the ninth planet? Nope, it got downgraded to a "dwarf planet" back in 2006. Oh, and don't get me started on how they used to teach that dinosaurs were cold-blooded - turns out, some of them might've been warm-blooded like modern birds! It's wild how science keeps evolving and uncovering new truths. #brightside

FunTranscript
00:00You're on a desert safari, but things don't go as planned.
00:05Now you've run out of water in one of the hottest and driest places on the planet.
00:11You might think you can get some water from a cactus.
00:13But sorry, that's just a myth.
00:16In fact, most cactuses have protective chemicals inside them that can make you sick if you
00:21try to eat them.
00:22There are only a couple of exceptions.
00:24The prickly pear and one type of barrel cactus called the fishhook barrel cactus have milder
00:29chemicals and could give you some water if you really needed it.
00:34If you believe you can escape an alligator if you run in a zigzag, well, I need to disappoint
00:39you.
00:40This isn't true either.
00:41Just run as fast as you can.
00:44Alligators rarely chase humans on land.
00:47They prefer to ambush their prey in the water, where they are faster and more agile.
00:52After all, they can swim at 10 miles per hour.
00:55So the chance of an alligator chasing a human on land is very low.
00:59This zigzag-running advice is more of a joke than a serious survival strategy.
01:06Don't believe the myth claiming you can survive a wild animal attack if you pretend to not
01:11be alive.
01:12Okay, in the animal kingdom, playing dead is a common defense tactic.
01:17Some animals even excrete certain odors to enhance the illusion and deter predators.
01:22Yet for humans, that's different.
01:25An investigation into 14 different types of animals in North America revealed that, in
01:30most situations, it's crucial to stay alert and knowledgeable to be able to take the right
01:35actions in time.
01:37The next popular, but false, idea is that polar bears hide their noses with their paws
01:42while hunting.
01:43People think they do it because their black noses are easy to see against the ice while
01:48their fur blends in.
01:49However, experts have spent years using telescopes to watch polar bears hunting seals in the
01:55Arctic.
01:56They've observed them for a long time, even up to 24 hours, and have never seen them cover
02:01their noses like that.
02:03Unless they have to sneeze.
02:05Just joking.
02:09Another belief is that running downhill will save you from a bear.
02:13This is based on the idea that their shorter front legs struggle to run downhill.
02:18In reality, bears are incredibly fast runners, capable of reaching speeds of over 37 mph,
02:25and they can sprint downhill just as easily as uphill.
02:28So you'll need another strategy.
02:31The myth that vehicle headrests are designed to be detachable and sharp to break windows
02:35is false.
02:37The primary function of a headrest is to prevent neck damage in a crash.
02:42Research and documents about the headrest design don't mention any feature for breaking
02:46windows.
02:47Thus, not all vehicles have removable headrests.
02:50And those that are detachable are not necessarily sharp.
02:57Touching a baby bird will make its parents abandon it.
03:00Actually, birds have a limited sense of smell, so they're unlikely to detect human scent
03:05on their babies.
03:06This misconception often leads people to leave fledgling birds alone, thinking they're helping.
03:11But in reality, these young birds might need assistance.
03:15But also, it's common for young birds to leave the nest before they can fly well, then
03:19their parents usually to continue to feed them on the ground.
03:23If you find a baby bird that has fallen out of its nest, it's best to leave it alone as
03:28the parents are likely nearby and will continue to care for it.
03:33The widespread belief that humans use only 10% of their brains is a myth too.
03:38Advanced neuroimaging tools like PET scans show that the entire brain is active, even
03:43during sleep.
03:45These scans reveal continuous activity across the brain, involved in functions such as regulating,
03:51interpreting, and acting.
03:53This debunks the idea that large parts of the brain remain inactive.
04:01The myth that shaving body hair makes it grow back thicker and darker is false.
04:07When you shave facial or body hair, it doesn't change its thickness, color, or rate of growth.
04:12Shaving just leaves hairs with blunt tips.
04:15These newly cut blunt tips might feel coarser or stubbier as the hair grows out.
04:21During this phase, the hair may seem more noticeable and could appear darker or thicker.
04:26But this is just a temporary effect, not an actual change in the properties of your body
04:31hair.
04:33The tall tale that daddy long legs are the world's most venomous spiders is just a bit
04:38of an overstatement.
04:39These critters aren't even true spiders.
04:42They have been wrongly accused of packing a dangerous venomous bunch.
04:46In fact, they don't have venom glands at all, and their tiny fangs can't even break human
04:51skin.
04:52It seems they got their fearsome reputation more from their spindly appearance and as
04:56a case of mistaken identity.
05:02The belief that everyone in medieval times kicked a bucket in their 30s is way off.
05:07Medieval life expectancy is just an average.
05:10Back then, a lot of people didn't make it past childhood due to things like rampant
05:14infant mortality and risky childbirth.
05:17But if you went through those early life hurdles and hit your 20s, you had a decent shot at
05:21seeing your 50s or even 70s.
05:24Most of our medieval life expectancy data comes from noble dudes, who often ended up
05:29as battlefield statistics, skewing the numbers.
05:34Soap is often seen as the arch-nemesis of cast-iron cookware, but let's bust that
05:38myth with a little kitchen science.
05:41The fear is that soap will take away the precious seasoning that makes cast-iron pans non-stick
05:46and awesome.
05:48Modern soaps are much gentler than those old lye-heavy ones that started this whole non-soap-on-cast-iron
05:53rule.
05:54These soaps won't harm your pan's seasoning, especially if it's well-established.
06:04The old wait-an-hour-after-eating-before-you-swim rule is more of a misconception than a medical
06:09must.
06:11The idea was that swimming right after a big meal could lead to cramps.
06:15But in reality, it's not a hard rule.
06:18Sure, your body diverts blood to your stomach for better digestion, which could, theoretically,
06:24save less for your muscles, increasing the risk of cramps.
06:27But for most people, a little light post-snack swimming isn't a recipe for disaster.
06:34Bundling up because you think cold weather causes colds?
06:37Well, it's not exactly the air that's to blame.
06:40It's true that we often start sniffling when the temperature drops, but it's not
06:44the cold itself doing the deed.
06:46The real culprits are the viruses that cause colds, which just happen to love those lower
06:52temperatures.
06:53So while chilly weather provides a cozy playground for these germs, catching a cold still requires
06:58catching the virus.
07:00In other words, it's not the frosty weather, but the frosty-weather-loving viruses that
07:05you need to watch out for.
07:07Oh look, it's that time again when a Facebook privacy hoax makes the rounds, convincing
07:14people that a simple copy-paste can magically protect their data.
07:18Yes, the classic I-do-not-give-Facebook-permission spiel is back, charming users into thinking
07:25this status update is a legally binding shield against privacy breaches.
07:29Spoiler alert, it's not.
07:32These posts claim that declaring sovereignty over your personal content on your timeline
07:36will stop Facebook from using your photos, information, and messages.
07:40Facebook's actual policies and user agreements, which everyone agreed to by signing up, still
07:46hold the real power.
07:51Shaving a double-coated dog is okay?
07:53No, it's a big no-no, with some lasting downsides.
07:57These dogs have a soft undercoat and a tougher topcoat.
08:02Shaving messes up their growth balance, leading to a mismatched and not-so-pretty coat.
08:06Plus, there's only a 50-50 chance the double coat will return to its former glory, if at
08:12all.
08:13According to a popular belief, shaving doesn't cool them down.
08:16It actually wrecks the coat's natural air circulation system.
08:20Other risks include matting, sunburn, and impaired temperature regulation.
08:25The coat might never look or feel the same again.
08:28Go for a de-shedding treatment.
08:30It removes excess undercoat, helps your dog stay cool, and keeps the coat in top shape
08:35– all without the drama of a full shave.
08:40It's time to look at common misconceptions and myths associated with treating frostbite.
08:45Rubbing frostbitten skin cannot help.
08:48It can actually worsen the condition and lead to tissue damage.
08:51The idea that hot water should be used for re-warming the affected areas is wrong, too.
08:56Use lukewarm water instead to avoid burns.
