Kind: research · Impact: medium

## In brief

- A study of 18,476 people aged 1 to 96 examined whether blood chemistry can indicate how fast a person is aging.
- Some participants had blood chemistry that read older than their birth certificate age.
- Those participants went on to be associated with future disease and early death, according to the Earth.com report.

## Why it matters

If a routine blood draw can reveal biological age, it could offer a practical way to identify people at higher risk of future disease and early death.
