If I'm not doing math, then I'm probably either
  • playing a game (maybe squash),
  • playing my bouzouki or mandolin (or trying to),
  • listening to music (preferably live),
  • traveling,
  • hiking, or more like hillwalking (less of this in Michigan),
  • reading a book,
  • cooking/eating - probably Greek or Thai (if I'm not being lazy),
  • drinking some tea (preferably sencha), or
  • hanging out with my cats.

Here I am petting an elephant in Thailand.
