There IS a relation between the physical aspects of our body and our mental game. They cannot be fully separated. Our brain itself is a physical asset. To sit in a chair and use a keyboard requires a level of physicality.

But with programming the age of being set out to pasture is much higher compared to sports or physical jobs. I've witnessed first hand guys in their 70's crank out productivity and creative ideas. One of the UNIX guys recently cranked out some new software in his 80's.
