I'm approaching 40, and have so much more I want to learn. The only thing is I hope I keep my physical and mental strength going long enough. My plan for this right now is to keep physically active. Cycling to work (2x9km), and 2-3 weekly 5-15km runs. Seems to work reasonably well, though I see I would do better if I increased the running even more, perhaps switching out some of those bike travels to running to work instead etc.
