Can a 10-Second Balance Test Predict How Some People Live?

A new study suggests if you can't stand on one leg for 10 seconds it may mean you won't live another 10 years. Medical researchers monitored hundreds of volunteers who agreed to do the 10-second challenge every year for 7 years. They found that those who failed the test died sooner than those who passed. People are now posting videos of themselves trying out the 10-second balance challenge.
