Below are some of the things I used to do when I was not doing math; now I pretty much just hang out with my daughter.
  • play games,
  • play my bouzouki or mandolin (or try to),
  • listen to music,
  • travel,
  • hike, or more like hillwalking,
  • read a book,
  • cook and eat,
  • drink tea.

Here I am petting an elephant in Thailand.
