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.

1. I was told there would be no math

People in the US are living longer (and elsewhere, too, surely). Healthcare spending in the US is expected to increase from 5.5% of the economy today to almost 9% by 2046. But why? With most healthcare spending occurring in the last five years of life, that spending is fixed, and an increasing life expectancy should just push that spending out a few years. Several studies suggest that technology is a major cause of healthcare spending increases, accounting for as much as one-third to two-thirds of the increase. And technology, while good, is expensive. Just ask someone with a heart condition or ask a premature baby how technology helped them. They can answer because they’re still alive. That’s right. Our premature baby talks. So?
