As anti-aging regimens and longevity treatments continue to gain traction, a new study suggests that humans may have reached a roadblock on their quest for longer lifespans.
On Monday, Nature Aging published an analysis suggesting human life expectancy is plateauing after decades of progress.
Lead study author S. Jay Olshansky, a biostatistician at the University of Illinois, Chicago, told Business Insider's Hilary Brueck, "We've got a lot of people making it out to 85 or 90" but "100 isn't going to happen for most people."
According to a 2022 report by the CDC's National Center for Health Statistics, the average life expectancy in the US was 77.5 years. However, the value varies across states, as factors like environment, diet, exercise, genetics, access to healthcare, and other lifestyle choices contribute to differences.
Using the CDC's National Center for Health Statistics 2021 report — the most recent CDC state data available — here are the five states with the longest life expectancies and the five states with the shortest.
