Bryan Johnson tracks his biological age against his chronological age using 100 markers. His body temperature runs 3°F cooler than average, and he argues that slowing your pace of aging is the real measure of health, extending years of productive life.
The longer you're well and healthy, the longer you can be engaged in productive activities. Yes, I've got 50 perfect biomarkers. Yes, my body runs 3 degrees Fahrenheit cooler. And yes, I have 100 biological age markers less than my chronological age. But to me, that speed of aging is really the most significant thing. Because you think about it, it's almost like the new wealth creation.
