What is the purpose of the indentations on the inside of our upper forearms?

Question

I understand that not all people have them, and I don't know if many notice.
But right before your inner elbo, in that soft underside of our (well, some) upper forearms, are these horizontal indentations. Their very faint, and are almost invisible.
Some have it on only one arm, other on both, some on none.

I've only heard it being aknowledged by some of my asian friends, who say that there's a legend in some places in China that says if you have one dip, it means you can hear ghosts, and two mean you can see them.

Now whether or not that's true, I still would like to know if anybody knows it's name, purpose, or function. Maybe even more mythology.

Anybody?
Grazi.

Answer 1

They are called dimples...........like some have on their chins, cheeks, buttocks, I have them on the backs of my knee bends.

Answer 2

I don't know what it called, but I do know that the myth surrounding them have some truth.
I have two, and one another two friends who both have two as well, and we often see or feel strange things concerning the paranormal. Now, I'm not a medium freak person, but I do believe in ghosts, and I have heard them, etc.
Other people I know have none, and they don't sense anything strange at all.
My father has two, and he sees and feels things a lot.
My sister only has one, so does my mom, and they have only about half the feeling concerning weird things.
Hope I helped you out.
P.S - I love having two!

Answer 3

I have no idea why we have them. I hope that the myth is true. I wish I could tell you a good answer but I dont have one. I have always wondered why they where there. I have a line on both my forearms and one on my upper arm.
