WHEN NAPPING GOES BAD. “It’s never occurred to me to study my naps, or chart them, or pick them apart for quality. There are good naps and bad ones. There are short naps that leave you refreshed, and short ones that leave you groggy. Long ones that seem to add a year to your life, and long ones that make you feel as though you emerged from a bog of tar. To be fair, long naps never leave me logy. Short naps can make me feel angry, because they weren’t longer naps.”
