You pretty well know mine: I figure skate, I dig ponds, I keep a reef, I look up ancestors, I look up other things, I follow physics and archaeology and dabble in languages, I draw, I photograph, I travel, I like code, crossword, and jigsaw puzzles, particularly the electronic sort.

Among things on hold, I love camping, riding, swimming, but haven’t done it in years; I used to love fishing, but I’ve nursed too many aquarium fish by now. I’m only happy if I don’t get a bite. I like model building—we’ve got some lovely wooden ship models that have been languishing for 3 years, awaiting spare time.

Things I’d rather go to the dentist than do: go shopping, hike on bare, flat ground, go to a nightclub, a tanning salon, a spa, a manicure, or a beauty parlor.
