Roller skating and inline skating have been gaining popularity for the last five years or so. I took it up (sort of again) in my late thirties, due to my son being invited to a roller skating birthday party, and discovered how much I enjoy it as both a challenge and Zen-like experience of focused concentration on both nothing and 'everything going on around me'.

I only do it at a rink and in that context I love it. I look forward to it in a way that makes me feel like a child, so much so that it makes me question my own maturity / adulthood, but nowhere near enough to suppress that enthusiasm.

I'm currently learning to skate backwards, and enjoying the total inability to learn it theoretically, you can only improve by doing, and at my age it has to be done slowly and incrementally because injuries mean you have to wait so long until the next time you can go again - so there's a brake on the speed of improvement.

I really still feel that childish excitement about going skating.
