The Craziest Human Appendages: Finger StomachTwenty-year-old furniture maker, Wang Yongjun lost the tip of his finger when working with an electric saw. Eeek! His doctor had to make a snap decision to save the finger with this unusual technique -- making a faux umbilical cord-type thingy to restore blood flow to the tip of the digit and help regenerate a new finger.
