Another reason to ride to work

While riding in this morning I heard this story on the news http://www.bbc.co.uk/news/health-11664660

This is yet another reason to ride to work everyday and get 2 imune system boosts per day. I very rarely get colds and never get too affected by them although reading the report I would seem to be in the best category. I ride the bike 5 days a week, I am older, married and eat lots of fruit.

All good stuff.
