When I'm not working, working on writing a book, or working, I get the chance
to do some of the following, sometimes even with my family:
Aikido - much fun - difficult to find
local
clubs though.
Ski - usually in Austria (because its only 1 hour away ;-)
Climbing - in the past,
(back when I was young, fit and non-vertiginous), these days a very mild and occassional
Klettersteig is the limit - I can tell you.
