Survival of the fittest: exercise 'can fight ageing'

Might work for some. I am not a believer in "anti-aging." I think it is a marketing scam.

"Long-term physical activity has an anti-ageing effect at the cellular level, a German study suggests.
Researchers focused on telomeres, the protective caps on the chromosomes that keep a cell's DNA stable but shorten with age.

They found telomeres shortened less quickly in key immune cells of athletes with a long history of endurance training."

Now, they have to explain Jim Fixx (and others).

Fitness can, however, add life to your years.
