Longevity tests aren't always all about how long you can run on a treadmill or whether you can touch your toes. That said, there are five longevity tests I would recommend trying if you are looking to assess your balance, strength and mobility as you get older.
The natural loss of lean muscle mass and strength later in life (if not built or maintained) can impact your balance, so if you've noticed falls or trips have become more frequent, it could be time to test your balance.
