A review of INTERNAL TIME: Chronotypes, Social Jet Lag, and Why You’re So Tired.
By Till Roenneberg.
It’s late, and, as always, I have lots of things I’d like to do before I go to bed. I don’t sleep much. I enjoy being awake. My dreams are quiet, but my days are full of things to explore, the treasures of ordinary life. So when I began to read Till Roenneberg’s Internal Time, a book whose dust jacket mentions sleep and biological clocks, I was hoping to find a passage clearly stating that those who sleep less are happier and wiser, and live longer, or at least are more interesting to talk to at parties. I didn’t find it, but the book was fascinating, and so I read on, and now, at 11 p.m., I have begun to write.
