I am friends with a hand surgeon. At home one weekend I severed the tendons that extend my fingers on a sharp metal edge. My friend fixed it. During the surgery he woke me up long enough to show me that he had repaired each tendon with different colored sutures and if I moved my fingers it would look just like that scene in T2 where Arnold demonstrated to the scientist that he was really a cyborg. He was right. It looked just like that. Very cool, but it's been heavy leather gloves around sheet metal since.
