Older Athletes Have a Strikingly Young Fitness Age
Turns out that the 4200 seniors they tested from the Senior Olympic Games showed an average chronological age of 68, but their average "fitness age" was 43.
They haven't broken the numbers out by sport, although they are working on it. Naturally, the author of this article (MYT, natch) sounded just a leeeeetle biased in favor of "endurance sports such as distance running and swimming," (sports that NYT readers probably pursue more often than thuggish exercises like weightlifting), but as I say, nobody knows, because they haven't generated those numbers yet.
I'm about that average age. I dunno if I feel 43, (that's long enough ago that it's hard to recall memories of general fitness) but I don't think I feel 69, either. Whatever that is supposed to feel like.
