Not really. As early as my 20s, and certainly all through my 30s and 40s, I didn't move enough, meaning that I couldn't do ordinary stuff, such as squat deeply. Then, all through my 50s, I focused on engaging in diverse movement—initially just exercise, but broadening out to non-exercise movement as well. Pretty much all through my 50s I moved better every year than I had the year before—hence better than I had since I was a teenager.

You should come for a visit! We could go for a hike, hit the weight room, maybe play with my gymnastic rings. I could show you the stuff I do with kettlebells and heavy clubs (and I just ordered a mace!). Oh, and you could come watch me train with the other sword fighters. I think you'd be impressed.
