NYT article on exercise and aging

[Wahine]

The article was really interesting, but made me feel like a wimp....
I guess I should stop concentrating on how far I ride and think about how hard I ride.

Actually Robyn, I would say that is not a good idea for you right now. You're still recovering (correct me if I'm wrong, I don't remember all the details) and intense exercise is more likely to put you back into that weird fatigue cycle than 60 to 70% effort right now. When your other stuff is better. Then you can ride hard. But it is true that including hard efforts in your workouts becomes increasing important as you get older.

I met a 108 year old masters swimming once. He always won his events. His advice: "If you can't beat them, out-live them."
