Fair point, but compare full-time workers to people aged 75+ (who are mostly retired): the latter have 4.5 hours more leisure time per weekday, and 60% of that is spent watching TV. The category most likely to contain creative hobbies ("Other leisure and sports activities, including travel") gets an extra 4 minutes per day. Education time rounds to zero. They do read more, though: about an hour more per day.

Dropping back to ages 65-74 is mostly similar, except they only read half as much.
