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 no regrets in my life even the crazy things I've been in. It all made me the I am today and I wouldn't change anything. I'm happy with who I am!
