I was studying chemistry, and this is a physically hard job because you are in the laboratory, you work hard, and you come home in the late afternoon or in the evening and you always needed a break.

For a long time, I felt instinctively irritated - sometimes repelled - by scientific friends' automatic use of the word 'mechanism' for automatic bodily processes. A machine was man-made; it was not a sentient being; a man was not a machine.
