I like that expression, "biking old."
That's what's wrong with me!
Seriously, I think you are right, here. Even if you are the fittest athlete around, eventually, something's gotta go south as you age. And yes, I think Lance has mentally checked out, which is fine. I like him, but I also like several of the other riders and I have learned a little more about some of them, without all of the focus on Lance.
