I knew of a physicist at the University of Chicago who was rather crazy like some scientists, and the idea of the insolidity, the instability of the physical world impressed him so much that he used to go around in enormous padded slippers for fear he should fall through the floor.
I have a really great family, and when Im not filming, I go home and walk the dogs, take out the garbage, clean my room, all that stuff. My family and my friends keep me in line, and make sure I dont get crazy.
