Age?
I'm that same age still skateboard and I drop in on 20feet high half pipes and still can ollie off of the back of an 18wheeler trailer.
Big plus I don't even come close to as healthy eating as Scott does nor drink enough water. I've had 4concusions,broken arm,feet several,two broken jaws,3 ripped off and sewn back fingers and just last Aug I shattered my knee cap and shitload of cartlidge.
I'm completely straight as a pin and don't have an ache anywhere even when it rains.
