I started running last fall, but it's boring as hell so in the spring I picked up skateboarding (at 40). It's the steepest and most rewarding learning curve I've been on for a long time. The downside is that all I can think about at work is what I'm going to do when my rickety old body has repaired itself well enough to skateboard again. I'm pretty sure that's a good indicator I'm stimulating parts of my brain that haven't been challenged in a good long time.
