From a medical standpoint one can not necessarily judge the inside from looking at the outside.

That said I have followed Serge´s carrier for two decades. He is truly awesome and healthy looking at his age. Problem is he might be as close to a coronary life threatening event as anyone in his age group. To be able to sustain that perfect exterior he would of course have to be pretty healthy overall, but many essential parts of the body will not respond as much to training and healthy life style as the muscles.

For anyone having trained hard in the gym, he is obviously an extremely impressive sight though.

I believe nutrition and genetics is far more important for longevity than training muscles.
