They can touch their toes easily.
And they can sit crosslegged on the floor from a standing position, and stand back up again without having to place a hand or knee on the floor more than once.
How easily you can touch your toes is an accurate reflection of how healthy your arteries are, while the stand-sit-stand test is a reliable measure of your musculoskeletal fitness, which is a good predictor of mortality. If you have to use your knee or hand for support more than twice during the whole sit-stand movement, your risk of dying in the next handful of years more than doubles.
STEAL IT: Take up yoga. Not only do the same stretching exercises that make you flexible help to slow age-related stiffening of the arteries, maintaining flexibility, muscle strength and coordination has a positive impact on your life expectancy, too – and yoga does all three. #
