64 Ways Your Own Body Can Surprise You

Hey guys! Here's another compilation of weirdly fascinating facts about the human body! You think you know your own body perfectly? Well, you probably know how it works and what kinds of changes and processes are occurring in it every second of the day. But in fact, the human body is one seriously complex and mysterious mechanism. And there are really surprising facts you might never have guessed!

Did you know that your body is ever-changing? When you’re born, you have around 300 bones. By adulthood, 1/3 of those have fused together to leave you with just 206. And you’re technically missing kneecaps until about age 3. Also, you “replace” your skin entirely every month, your blood – every 4 months, the liver – 500 days, and you make yourself new bone cells every 10 years!

Don't Leave a Glass of Water Near Your Bed

You’ve heard it for as long as you can remember: “Drink lots of water!” So, to make it easier on yourself, you keep a glass right by your bed to drink from in the evening and morning. But, uh-oh, looks like that could be a big mistake! Wanna know why it's bad?

Well, first of all, it’s unsanitary. It could be dust, debris, or even a fly or mosquito that makes its way into your nightly source of hydration. And in your zombified half-asleep state, you won’t even notice that thing floating in there when you take a gulp in the morning! And what can present a real threat is bacteria! Sitting water can become a breeding ground for germs! But these are not all reasons.

#water #healthylifestyle #brightside

SUMMARY:
- Each time you take a sip, you leave a little backwash in the glass. Well, your mouth is full of bacteria, and if they sit in that glass all night, they have all the time in the world to multiply.
- Water that’s exposed to air will go through some chemical changes. When you leave it out and open overnight, carbon dioxide makes its way into the glass.
- With a glassful of water right next to you, you might be tempted to grab it anytime in the night. Of course, if you’ve got liquid going in, then it’s going to need to come out.
- If you have tap water in that glass, the chlorine added into it for disinfection will evaporate overnight.
- If it just so happens that you keep your bedside water not in a glass but in some plastic bottle or cup, it could contain the chemical bisphenol-A or another similar substance used in plastics.
- Finding a BPA-free bottle for your bedside water does eliminate the issue of plastic chemicals…but not the bacteria.
- If you happen to swing your arm out or push your pillow into that glass, causing it to spill, all the electronics nearby can spark out.
- Just have a fresh glass in the evening, and do it at least 2 hours before bed. That way, it won’t disrupt your sleep.
- Warm water leads to improved blood circulation. Then again, German scientists found that drinking cold water can raise your metabolism.
- Dehydration becomes life-threatening if you lose more than 10% of your body water. And don’t forget, 60% of your body is water!
- If you go beyond the amount of hydration your body needs, you risk getting water intoxication, which can also be life-threatening!
- Without you knowing it and with almost no effort except drinking water, your intake will cleanse your body of unwanted toxins.
- That detoxification process through water will also clean your skin.
- Water helps wash away leftover food particles and bacteria in your mouth.
- A 2014 study found that drinking water affects your mood. When those with low intake increased their water consumption, the increase in positive emotion and calmness was evident.
- Research shows that dehydration may lead to impaired thinking and reasoning.
- You ever heard that your body needs fiber to maintain healthy digestion and regularity? Again, without water, that won’t do you much good.
- If there’s one system that’s going to benefit a lot from drinking plenty of water, it’s got to be your kidneys and urinary tract.

How sharks can smell blood?

How sharks can smell blood? - Even though there’s just a 1 in 3.7 million chance of being killed by a shark, people are so fearful of the predators that they’ve developed myths about them.

Can Sharks Smell Blood from Miles Afar?

The chances that one day you will encounter a shark are minuscule, small, shall we say, teeny tiny. And still, there are dozens of frightening myths surrounding these predators, even though most of them are misconceptions. For example, everybody knows that sharks have a very developed sense of smell that’s hundreds of times stronger than yours.

It's probably no wonder that sharks can detect tiny amounts of different substances in the water, right? But what about the belief that sharks can smell a drop of blood from miles away? Is it true? And how much time will you need to get back to the safety of the beach and get a band-aid if you, say, cut your foot on a sharp stone while swimming in the ocean?

The average shark's lifespan 7:29
Do sharks swim in reverse? 8:27

#sharks #survivaltips #brightside

SUMMARY:
- While some shark species can identify the smell of blood from a quarter of a mile away, it doesn't reach them right away.
- Even though some sharks can decipher smells better than others, no shark will be able to smell your blood in the water from farther than a thousand ft away.
- By the way, few people are aware that sharks aren't that interested in hunting humans. Most of them are very particular about their diet.
- There’s a stereotype that sharks purposefully hunt humans. But most shark attacks happen because these predators mistake swimmers for their usual prey.
- A few shark species won't be able to breathe if something prevents them from moving. But the rest of the predators use either both breathing methods or the buccal pumping method, and can easily rest on the seafloor.
- It’s been said, If a shark is heading toward you, hide among jellyfish. Well, if you want to waste your time and hurt yourself, go ahead.
- It's another common misconception that all sharks are predators.
- Some sharks can even be found in lakes and rivers with fresh water!
- Among more than 400 species, there are both tiny ones, like the 8-inch-long deepwater dogfish, and impressive giants, such as the 40-ft-long whale shark.
- Despite their reputation as merciless and fearless monsters, you can stare a shark down or intimidate it.
- Sharks hang out mostly close to the surface. If you hear this statement, you should remember that it's nothing but a misconception.
- Sharks can attack and bite from any angle.
- The average shark's lifespan doesn't usually exceed 70 years.
- Sharks do NOT have a tongue, despite what some movies may show you. On the other hand, they have something that looks similar to the human tongue, but this organ is called the basihyal.
- Sharks do not and can not swim in reverse. Their tails propel them, and their pectoral fins help them to keep balance and turn.

What is likely happening is that the sharks can smell the blood but it's just not in a quantity that is interesting to them especially since they don't love human blood that much (btw, I spoke with a marine biologist and mammal blood is all the same from a chemical marker stand point so cow blood is a suitable substitute for human blood). If I did the experiment again, I would want to test human blood vs. fish blood. 

This is the most definitive study done to date in a control lab environment on what is least and most interesting to them: The Biology of Sharks and Rays Peter A. Klimley and Steven Oerding; ISBN-13: 9780226442495. Particularly pages 134-140. Figure 6.7; Table 6.2

The Only Way to Survive When You See a Shark

Out of the nearly 500 different species of shark that inhabit the oceans today, only a dozen or so have ever been known to go after humans. And even in those cases, it’s only believed to have happened because the shark was confused or curious. So, despite what movies like Jaws or The Meg have shown us over the years, there aren’t any sharks roaming near the shoreline, looking for people to eat.

In fact, sharks tend to prefer smaller fish and invertebrates. When it comes to us, it’s an old cliché but it rings true – they’re more scared of you than you are of them. Of course, everybody should know how to decrease the chances of encountering a shark. And if you happen upon one, here's what you should do.

TIMESTAMPS:
How to avoid a shark encounter 1:40
If you see a shark:
- Don't freak out 2:57
- Avoid sudden movements 3:49
- Keep the shark in front of you 4:28
- Make yourself appear as large as possible 5:24
- Use your camera or snorkel 6:25

#sharks #survivaltips #brightside

SUMMARY:
- First, always swim with a group. Sharks are significantly less likely to go after a group than a solitary person.
- Second, avoid the water at dawn, dusk, or night. Unless the water is in your swimming pool, then you’re fine.
- Avoid wearing shiny jewelry. This can have the unintended effect of making you into a human fishing lure.
- Sharks can smell blood from at least 500 yards away, if not more, and can easily track its source.
- If you see a shark while you’re in the ocean - Don’t. Freak. Out.
- Avoid sudden movements. That said, if there are people around, it’s a good idea to let them know what’s happening, so they can help – or if they didn’t watch this video, let them freak out and distract the shark for you.
- Try to keep the shark in front of you. Sharks are known as “ambush predators”, meaning they prefer to get to their prey by surprise.
- If you can’t get away, and the shark begins to circle or zig-zag around you, it’s time to go into survival mode. In this instance, try to make yourself appear as large as possible.
- If you happen to have a camera or snorkel, consider using this to go after the eyes or the gills.
- Many species, like the hammerhead, are critically endangered, so if you do come across one, stay cool and only defend yourself if necessary.

One Drop of Blood...Diver Cuts Himself Open While Swarmed by Sharks

We've all heard that sharks can smell one drop of blood in an Olympic size swimming pool. What's that mean for you and me? Watch and find out.
_____________________________________
Perhaps it's the fact that we aren't participating members of the food chain that causes us to forget that the ocean is full of other scents...scents that the sharks are also keenly aware of. Why exactly do we think they are going to drop everything they are doing and be more interested in our blood? Sharks have jobs to do, niches to fulfill, and have been doing so for millions of years. We don't have anything to do with that. As @Chris neff says, We're in the way, not on the menu
