lol that is not true, being physically fit has nothing to do with that. He is like Davenport and Steffi Graf. They look older when they were in their 20's and they doesn't seem to age since then. It is more genetics that anything else.
Having a little extra weight makes your face look younger. This is obvious, just look at the people you see every day. Guys who are obsessed with exercise might be physically fit, but their faces look drawn out and gaunt. Why do you think like every celebrity over 40 gets collagen injections to plump out their face? Either way, the point I was making is that it's stupid to predict how well Roger is going to age when he is still barely into his 30's.
