New research shows we evolved to get more active as we get older—and it’s never too late to start.
One major example, researchers suggest, is maintaining a high degree ofDespite previous assumptions that our ancestors had short lifespans, that’s been disproven by fossils indicating it was common for people to live into their 70s, the researchers note. They found that exercise likely had notable benefits that enabled longer life. These benefits include enhanced blood flow, reduce fat storage, efficient repair of DNA processes, and release of anti-inflammatory compounds.
All of these processes enabled hunter-gatherers to live for decades past their reproductive years. In what researchers call the “active grandparent hypothesis,” they suggest that evolution favored humans who engaged in lifelong physical activity, because it reduces vulnerability to chronic disease. “As a result, extended human healthspans and lifespans are both a cause and effect of habitual physical activity, helping explain why lack of lifelong physical activity in humans can increase disease risk and reduce longevity,” they write in their conclusions.
But even with evolution on your side, what if you’ve been skipping the impulse to stay active as the years pass? Or maybe you’ve been, but don’t feel quite as ramped up physically as your hunter-gatherer ancestors might have been. The good news is that it’s never too late to catch up.
