The longevity industry is coming off perhaps its best run on record. The expected span of an American life has increased by about three decades since 1900 to around 78 as of 2023. But for many people, even 78 years just won’t do.
The Methuselah Foundation, a biomedical charity, for example, wants to “make 90 the new 50,” and scientists at one biotechnology firm have argued that, unencumbered by disease, the body could potentially make it all the way to age 150. Even more optimistic estimates put the number closer to 1,000.
