From The New York Times:
"Wake up, America! Fully one in three adults admit that on any typical day they take a nap, according to a national survey released Wednesday.
"The proportion of self-proclaimed nappers was even higher among adults who had trouble sleeping the night before and who had exercised within the past 24 hours. It was also disproportionately higher among people who are poorer, black, men older than 50, men and women over 80 and among people who are not happy."
Whew! Thank God I'm a poor black octogenarian who exercises every day, or else I might suspect that I've been quite unhappy these past ten years!
