I enjoy the usual things such as reading, music and films and in my spare time practice karate where I've reached second kyu and am hoping to grade again soon!
I also play guitar which is a great way to relax but plectrums do wander off if you don't keep an eye on them and am looking into rock climbing and free diving for another hobby.

Coffee or possibly mini-golf., never the movies for a first date, it's hard to talk to your date without upsetting your theatre neighbours.
