Could humans live up to 150 years one day?
26 Jan 2026

Geneticist Steve Horvath has predicted that humans could eventually start living up to 150 years. The prediction is based on recent advancements in biological clocks and rejuvenation research.

Horvath, who created the first widely used epigenetic "aging clocks," emphasized the importance of accurately measuring biological age in longevity research.

This progress has enabled scientists to test treatments that aim to slow or potentially reverse the aging process, instead of just treating diseases.

Horvath's breakthrough in measuring biological age
Innovation impact

Horvath's work in the early 2010s revolutionized longevity research. He developed a test based on DNA methylation, which estimates a person's biological age across tissues.

This gave scientists a way to quantify aging itself, instead of just relying on years lived.

Horvath later expanded this into more advanced clocks like GrimAge, which predicts the mortality risk based on biological signals rather than chronological age.

Stance on extreme lifespan extension
Realistic expectations

Despite his confidence in reaching 150 years of age, Horvath dismissed the idea of humans living for 1,000 years as "totally science fiction."

He stressed that today's science is focused on realistic gains rather than immortality.

However, he did claim that sustained biomedical innovation over decades could meaningfully reshape human longevity, albeit not to fantastical extremes.

Vision for future biomedical innovations
Future prospects

Horvath envisions that if humanity can avoid disasters like nuclear holocausts, wars, and pandemics, we could find ways to drastically extend lifespan.

He said, "Imagine we have 100 more years of biomedical innovations — what will that do for health?"

This statement highlights his belief in the potential of future scientific advancements to significantly improve human health and longevity.
