Life is full of surprises. One of the greatest can be seeing someone resurrect from the great beyond. That's usually a fantastic soap opera trope but it can happen. Also the things we all can survive, witnessed by those in medicine, is astonishing. The human body and spirit can be miraculous.
Doctors see the darnedest things. Day in and day out they are faced with some of the craziest life has to offer. Any regular person wold be passed out on the floor and the injured would have to fend for themselves. Who would have thought that more than half of the shock we see on "Grey's Anatomy" can actually happen?!
