From an interview with poet William Bronk (1918-1999):
I'm glad I read the things I did when I was younger because I couldn't possibly do it now. I read Proust two or three times. Time is not a uniform quality because as you get older it shrinks. I don't know where the hell it goes to. There used to be long days when you could read long books but they're not there any more.
