The BBC has the article on its web site – see link above
Quote from the article :- ‘Doing lots of exercise in older age can prevent the immune system from declining and protect people against infections, scientists say.
They followed 125 long-distance cyclists, some now in their 80s, and found they had the immune systems of 20-year-olds.’
Now I know why Roy Connell and Ian McLean have had me out cycling, they think I’m elderly!
With ‘thanks’ to Roy Connell for the lead to this posting
