JJ Virgin identifies VO2 max, the maximum oxygen your body uses during intense exercise, as the strongest predictor of how long you'll live. She also argues for measuring bone density in your teens and twenties, before loss starts, rather than waiting until after menopause when damage is already done.
You've lost VO2 max. VO2 max is a measurement of how much oxygen you can convert into energy when you're working full out. It is biggest predictor of all-cause mortality or how long you will live. And then the other piece of this puzzle is bone mineral density, which reality is, and if you guys have kids, people should have their bone mineral density tested in their teens. Our teens and our 20s are when we lay down all the bone. And yet we wait till someone's postmenopausal to test their bones when that egg has been scrambled, you know, and now you're trying to unscramble it. It's ridiculous and crazy. It doesn't make any sense.
