I can bend my thumb towards my wrist, forwards and backwards. ( Backwards Picture here http://i37.photobucket.com/albums/e71/AmandaMayyy/hand.jpg ) It doesn't show it all the way, but I can.
I can lock my fingertip. Picture here - http://i37.photobucket.com/albums/e71/AmandaMayyy/Picture023.jpg
I can also touch my head to the back of my knees, foot behind my head, foot to my hip, and a buncha other things.
I'm pretty sure a lot of them come from being a vegetarian and not getting protein. :P
