Our hands are pretty amazing parts of our bodies. Think about all the things they can do! A person who knows sign language can count every number imaginable just by moving his or her hand in different shapes. Our hands can bend, they can stretch, they can wiggle, and they can wave! To be able to do that, the skin that covers our hands needs to be able to adjust to the changing shapes.
That's where those lines come in handy. They're technically called "flexion creases," and many of them are on our hands from before we are born! When our hands bend, the creases help fold the skin. Otherwise, whenever we made a fist, we'd just have this blob of loose skin hanging out under our fingers. Yuck!
Take a look at all those lines on your palms and fingers. Each one is there because it is at a place where our body bends.
Some people will say they can read your future by studying the lines on your palms. There isn't a science out there that supports that, but you can learn a lot just by looking at a persons hands.
You might see that a person bites their nails. That's probably a nervous habit. Maybe they're nervous about something. If a person has very rough skin and some scratches, it probably means they work with their hands. Maybe he or she does construction work? An easy thing to spot on someone's hand is a wedding ring. If you see one of those, you know they are married.
You might not be able to tell the future, but looking at a person's hands can tell you a lot about a person. Do your hands say something about you?
