text: what is the purpose of the indentations on the inside of our upper forearms? 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. they are called dimples...........like some have on their chins, cheeks, buttocks, i have them on the backs of my knee bends.
