The anti-aging industry in the U.S. is booming, valued at around $52 billion in 2024 and expected to exceed $100 billion by 2030. Many products promise to slow or reverse aging, but scientific research shows the reality is more complex.
While life expectancy has increased over generations—mainly due to better nutrition and medical care—scientists have long wondered if the biological rate of aging itself, known as senescence, has changed. Early work by mathematician Benjamin Gompertz in the 19th century showed mortality rates rise exponentially with age, like compounding interest.
A recent study by Silvio Patricio at the University of Southern Denmark revisited a 2010 theory by James W. Vaupel. Vaupel suggested that while aging is delayed by about a decade, the rate at which we age remains unchanged. Patricio analyzed mortality data from France, Denmark, Italy, and Sweden, adjusting for early-life deaths and historical events like wars and pandemics that affect mortality patterns across cohorts.
Patricio found that once these factors are accounted for, the rate of aging is remarkably consistent across generations. The small variations seen are due to historical “echoes” rather than biological changes.
“This means the biology of aging is stable,” Patricio said. “The differences we see are the cumulative effects of past events, not a change in how humans age.”
So, is the anti-aging industry selling false hope? Not entirely. While the fundamental rate of aging may be fixed, healthy habits like good nutrition, exercise, and sufficient sleep can improve longevity and quality of life.
In short, we cannot change how fast we age biologically, but we can influence how well we age.
