Better balance may mean a longer life
A study published online June 21, 2022, by the British Journal of Sports Medicine found that people who are unable to stand on one leg for 10 seconds in middle and later life have almost double the usual risk of premature death.
Researchers evaluated the health information and balance test results of 1,700 people (ages 51 to 75, and all free of walking problems), and then followed them for seven years.
