To glaze this donut, Gutman turns to science. He finds many studies but, apparently, few commas. Did you know, for instance, that “in two separate studies examining thousands of pictures taken from 1968 through 1993 and 1970 through 1999 researchers discovered that 55 percent to 60 percent of men and 80 percent of women smile in photos from pleasant public situations”? Me either.
I smiled more at David Dobbs’ cutting review of this book about smiling than I’d smiled at anything all day.
