A majority of young people seem to develop mental arteriosclerosis forty years before they get the physical kind. Another question: why do some people remain open and elastic into extreme old age, whereas others become rigid and unproductive before they're fifty?
Well, I'm in my 60s now. I finally look it, I think. People until I was 60 would always say they thought I looked younger, which I think, without flattering myself, I did, but I think I certainly have, as George Orwell says people do after a certain age, the face they deserve.
