[ meta-note: why is this flagged? we seem to be rather haphazardly applying the criteria "that good hackers might find interesting", especially given the number of hackers into life-hacking, surviving middle age and athletic behavior] Not a fan of running, but I am picking up way more BJJ classes than expected at my advanced age (46). Another factor that might help (aside from more free time, money, and the psychological factors in the article) is the fact that once you hit middle age, sporting behavior "is what it is". No-one expects that you're going to tear it up and compete with people in their 20s. I have found it way easier to maintain a focus on intrinsic achievements ("today I will do X because I want to and it's my goal") than extrinsic factors ("what people will think of me", "what I will look like") once Old Fart status is achieved.
