I would put motivation out of the equation, though, Fed seems to motivate himself with ease this days. Or that's what he wants us to believe in his interviews at least.
I agree with reflex/movement/flexibility - he's still pretty darn good in this department but nothing like he was in his mid 20's. The good part is that the decline won't be as visible as comparing a 24-year old Fed to a 30-year old Fed. I think a 35-year old healthy Fed would play comparably the way he does now.
