If you want to play hockey, you SHOULD. It's an awesome game. (: Find yourself a local ice or inline rink, and just get out there and do it. Get some skating lessons first if you need some, but if you know how to skate already, all you'll need is more practice and some protective gear. Hockey guys are nearly universally great people, and they will help you out.

I started playing hockey at 30, and started goaltending at 31, and have been playing about 4 years now. I'm the shortest player on the rink at 5'2", and I have a great time. So! If I can do it, you can do it! Go for it! (:
