Bending down to tighten your laces may be a little more difficult than it once was – but the trick is to keep running. In the view of a 99 year old man from Virginia, competing at the National Senior Games in Florida: “My consistent advice is to keep moving, keep moving, keep moving, and have a little luck.” And as a 90 year old woman from Maryland, also interviewed by the New York Times at the Games, observed: running is “just what I do. I feel good when I run, and when I don’t run it feels like I’m missing something. “Run every day, even if it’s a short distance. I can’t run very much now, but when I can’t run anymore I’ll still walk.”
