What age is the most active?
Our Bodies Age in Three Distinct Shifts, According to More Than 4,000 Blood Tests. In terms of biological ageing, the body seems to shift gears three times during our lifespans, new research suggests – with 34 years, 60 years and 78 years the key thresholds.
Whether you love it or hate it, physical activity is a cornerstone of healthy aging. Scientific evidence suggests that people who exercise regularly not only live longer, but also may live better — meaning they enjoy more years of life without pain or disability.
But it's not the only age-related change that can keep people from being physically active. As we get older, our skin, tendons, and ligaments become less elastic, which can lead to stiffer joints. We may also lose muscle mass and see a drop in our aerobic fitness. Plus, our reaction times may slow down.
