What to know about Biological age tests reveal what slows or hastens aging – but they’re useful only for researchers, not consumers

The article discusses the use of epigenetic aging clocks, explaining that while they are valuable tools for population-level scientific research, they are currently unreliable for individual health assessments. The authors argue that these tests lack medical standardization and can be influenced by transient factors and systemic disparities.

What happened

Imagine receiving a test result that tells you your body is biologically five years older than your chronological age.

Why it matters

You exercise regularly, get good sleep, eat healthy meals and have a happy personal life.

Common ground

Dozens of companies are marketing products that promise to reveal a person’s “true” biological age – that is, how well your body is functioning – for a price ranging from around US$30 to over $1,000.

Perspective signals

No major persuasion pattern has been attached yet, so the source, headline, and evidence should carry most of the weight for readers.
