With 3 young kids (aged 5, 4, 2) I don't get time for much to be honest.
I used to enjoy astronomy until I moved to a house with a garden enclosed by bloody fir trees. Can't see much now apart from the postage stamp sized bit of sky directly above.
I used to enjoy cycling but rarely get a free weekend now to escape town and really enjoy it. Cycling on urban roads is no fun at all. I do still follow the UCI road racing season on telly though.
I also used to play guitar etc etc etc
These days, I mainly enjoy going out for a run after I've put the kids to bed. I do the odd 10K race...thinking about a half marathon. Really must get around to joining a running club.
