I do Yoga. Like a lot of computer folk I spent my days sitting with terrible posture, and I love how it makes my back feel. If physical exercise is missing from your day, I can tell you that for me, adding it was trans formative. It's much easier to sleep well if you are physically tired too! In a big city, meetup.com will have a lot of interesting things happening every week, so rather than pick a hobby you might want to just make a point of doing a couple of those a week until you happen on something you want to do again.
