Have you ever noticed that your fingertips are winked when you’ve just finished swimming or washing dishes? It seems as if your hands have aged 30 years in a second. But is this an accident? Or is it something that nature has built into our bodies?

If your finger’s wrinkling up had no use at all, “ it wouldn’t need to.” Professor Tom Smulders from Newcastle University, UK, told BBC News. By studying wet fingers closely, Smulders and his partners found that the wrinkles looked a bit like the patterns on the car tire or on the bottom of the running shoes. So they made a guess that wrinkles on fingers might be able to help the hand hold things more tightly.

To test this, researchers asked 20 people to pick up marbles from water with their hands. But before they started, some of the people had to keep their hands in water for half an hour.

The researchers found that the people with wrinkled fingers completed the task the task faster than those with dry hands. But when they were asked to move dry marbles, all the people performed equally well, no matter they had the wrinkled fingers or not.

Our ancestors might not have played with marbles, but wrinkled fingers could have made it easier for them to climb around in the wet forests and catch fish from rivers, researchers say.

Similarly, our toes also get wrinkled in water. This may have developed from our ancestor’s need to run on wet ground.

But the question is, if wrinkled fingers are so helpful, why don’t our hands just stay that way all the time? Researchers explained that wrinkling has its disadvantage: wet fingertips are far less sensitive than smooth ones, reducing our sense of touch.

When you think of your hair, you probably think of the hair on your head. But there’s hair on almost every part of your body. (some places that don’t have hair include the lips, the palms of the hands ,and the soles of the feet.)

Some of the hair on your body is easy to see, like your eyebrows and the hair on your head, arms, and legs. But other hair ,like that on your cheek, is almost invisible.

Depending on where it is, hair has different jobs. The hair on your head keeps your head warm and provided a little cushioning for your skull. Eyelashes protect your eyes by decreasing the amount of light and dust that go into them, and eyebrows protect your eyes from sweat dripping down from your forehead.
