The KNEE LIFT!  I remember Demi Moore did this procedure years back (this pic is from last her knees look good to you? Haha what a weird question).

“Regardless of how young your face looks, the knee is a tell-tale sign of true age,” said Dr Michael Diaz, a board certified plastic surgeon based out of Melbourne, Florida. “The wrinkles on your knees act as tree rings on the trunk of a tree.”

Really?  Do THAT many people stare at knees to determine age?

Would you be down for this procedure? -_-
