Questions You Have Probably Asked About Your Own Body

1. Why do I have eyebrows?

If you've ever run to catch a bus, you know just how sweaty your forehead can get. Eyebrows are designed to prevent sweat from dripping down into your eyes. Think of them as a built-in headband.

2. Why do my fingers get wrinkly in the shower?

It actually has nothing to do with absorbing the water, and everything to do with improving our grip on things underwater. Think of it like the treads in a tire giving a much better grip in slippery conditions.

3. Why do my eyes water when it’s windy or cold?

When faced with wind or cold, your tear ducts pump out tears in order to prevent your eyes from getting too dry and to keep dust and particles out. I bet you wish you knew that when everyone on the playground said you were sad.

4. Why are my lips red?

Your lips, along with containing a very thin layer of skin, have a lot with fine-branching blood vessels called capillaries. So that pinkish hue is actually caused by a bunch of blood right under the surface of your skin.

5. Why does my blood taste like metal?

Blood contains iron, which is a metal. In fact, researchers say the iron smell is actually a type of human body odor caused by skin oils reacting with metals. So blood and skin would smell the same as the combination of coins and skin.

6. Why can’t I roll my tongue?

Around 65 to 81 percent of people can complete the party trick, which was long linked to genetics. However, modern day scientists have challenged that theory, saying it’s a bit more complicated than that.

7. Why do I have blue eyes?

Scientists believe blue eyed folks are subject to genetic mutation inherited from a single ancestor who lived somewhere between 6,000 and 10,000 years ago. Before that time, officials believe all humans had brown eyes.

8. Why do my fingernails grow faster than my toenails?

Ever wonder why you’re clipping your fingers more than your toes? Fingernails grow faster because more blood circulates through the hands than the feet. A better blood supply helps nails grow faster.

9. Why are my veins blue?

Despite actually being red in color, veins appear blue to your eye because while other wavelengths of light can penetrate the skin and are absorbed, the blue light is reflected back, making your veins appear blue.

Another Fact about Finger Nails
✅ On average, fingernails grow about 1/10 of an inch in a month. The fastest growing nail is the one on your middle finger. The slowest growing nail is your thumb nail. Freshly cut nails grow faster than nails that aren't cut regularly.

Why do our fingers and toes wrinkle up like prunes when we've been in the water for some time?

Things being what they are, how did researchers make sense of this? 

Researchers made sense of this by watching that the skin of individuals with nerve harm did not prune up when presented to water. This fundamentally implies if your skin wrinkles up when subjected to water for a long length, it is working regularly. Be that as it may, on the off chance that you don't encounter anything of this sort, it implies you experience the ill effects of nerve harm. 

 

Is there a purpose behind this wrinkling of fingers and toes?

Eric Schulze, host of Smithsonian magazine's online video arrangement "Ask Smithsonian" says, "Perhaps we wrinkle, so like tire treads, our fingers and toes can improve footing in wet conditions." Can this be valid? 

In fact, a study directed by researchers at Newcastle University, England in 2013 demonstrates that wrinkled fingers improve treatment of wet articles. Be that as it may, a different study directed at the Max Delbrück Center for Molecular Medicine in Berlin, Germany in 2014 denied any such plausibility as it found no such impact of wrinkled skin on hold.
