i don't know if any of you know billy cowan wha but he is also m houston. he's a harvard trained, baylor trained a surgeon but also a magician and plays trombone and a band. i don't think that he sleeps. and then he is also a spectacular inventor. one day he was in his office waiting every week he would see people with inventions just to tell them yes, no, maybe and there was some kid coming in from australia and he could barely bring himself to meet with the guy. he comes in with his backpack and takes out a device wrappeds in bags and said i think this would work as an art artificial heart and because billy is an inventor he looked at this thing and excuse me, she said holy shit this is it targets of the latest iteration i write about predominantly in my book has one moving part and that is the one that's about this big but they saw from a prototype that this would do it and they are all crazy. >> it seems like in this field you have to have a sort of daredevil side to you. you have plenty of anecdotes in the book about theot sort of bending the rules in
