Online gaming was my most recent hobby before astronomy. I gave it up because it took too much time and I didn't have time to play games and play astronomy
Little did I know this hobby takes up much more time than online gaming did
I've also played various sports competitively over the past 10 years (basketball and tennis mainly), but gave them up due to time, commuting to work, family etc.
My wife is into scrapbooking, and I just started doing a few pages to spend some quality time with her (ie: earn browney points!)
So that's my newest hobby. Don't know how long it will last though. It's fun though
Is browsing IIS considered a hobby? Because it takes up most of my time
