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.
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?
