Here are some of the things I do when not doing math:
- play games (a lot of squash lately),
- play my bouzouki or mandolin (or try to),
- listen to music (preferably live),
- travel (often related to math),
- hike, or more like hillwalking (less of this in Michigan),
- read a book,
- cook and eat - when I'm not being lazy I like to try to make either Greek or Thai dishes,
- drink tea (preferably sencha),
- relax with my family.
Here I am petting an elephant in Thailand.
