The biological metrics that reveal how our bodies age

If you only eat one bagel today, this is the bagel.
Summary
The article explores the subtle, measurable biological changes that occur as we age, focusing on objective metrics like kidney filtration rate, VO2 max, grip strength, and other physiological markers. It highlights that while most metrics decline gradually over decades, kidney filtration drops nearly twice as fast as other markers rise. Notably, a subset of people in their seventies maintain kidney function levels comparable to a thirty-year-old, suggesting that aging trajectories vary significantly between individuals.
Key quotes
· 5 pulledYeats wrote of an aged man as 'a tattered coat upon a stick.' But for most of us, aging comes as small diminishments.
The body is keeping score long before we are.
None of these metrics move more than a few percent in a year, but stacked across decades, they describe an aging body.
Kidney filtration falls almost twice as fast as any other lab marker rises.
A quiet subset of people in their seventies hold the levels of a thirty-year-old.
