Humans could theoretically live up to 156 years, study says - KTLA

What the report says

KTLA Los Angeles reported on a study suggesting that, under a highly theoretical model, humans might be able to live as long as 156 years. According to the limited source material available, researchers modeled a maximum human age in a scenario where major biological drivers of aging were removed, while still allowing for somatic mutations — genetic changes that accumulate in the body’s cells over time.

The report does not provide the article’s full text, the names of the researchers, the institution involved or the publication venue, so those details cannot be verified from the supplied evidence. The central claim, as described by KTLA, is not that people are currently expected to reach 156 years, but that a model produced that estimate under an assumed set of biological conditions.

For context, aging research often examines “hallmarks” or mechanisms associated with physical decline, such as cellular damage, reduced tissue repair and changes in how cells function. Somatic mutations are one category of age-related change; unlike inherited genetic variants, they arise during a person’s lifetime. A model that removes most aging-related damage would therefore be exploring an upper limit rather than describing present-day medicine.

The finding matters because it adds to debate over whether human lifespan has a fixed ceiling and what might be possible if future interventions could slow or prevent multiple aging processes. Based on the available KTLA summary, however, the study should be read as a theoretical exercise, not evidence of an existing treatment or a prediction that people will soon routinely live to 156.
