Sweet glutes and strong immune systems in old age

A study in the UK has demonstrated the immune-boosting effects of significant exercise during old age. 125 long-distance cyclists in their 60s, 70s, and 80s were tracked and their immune systems measured. Results showed that many of these elderly cyclists—riding 100km to 300km in a stretch—had immune systems that produce the same level of T-cells as healthy 20-year-olds. The effect of this, of course, is resistance to infection and disease. As one participant put it, “If exercise was a pill, everyone would be taking it.” Dilly dilly. Here’s all the commercials in order. And here’s a short story behind the use of that phrase and its appearance in US Bud Light commercials.
