The Longevity Boom: Between Science and Hype

Is living forever the next frontier of medicine, or an expensive illusion? As interest in longevity technology surges globally, scientists and clinicians are urging a more measured perspective.
Google searches for "longevity" tripled over the course of 2025, and the market has responded accordingly. At the Consumer Electronics Show in Las Vegas earlier this year, longevity technology was among the most prominent categories on display, with devices promising to calculate biological age, measure body composition, and assess health across dozens of biomarkers, some retailing for several hundred dollars.
Yet the scientific picture is more sobering. A study published in PNAS found a significant deceleration in life expectancy gains among people alive today, disrupting decades of steady progress. A separate study in Nature Ageing suggested that the proportion of people reaching the age of 100 this century is unlikely to exceed 15 per cent for women and 5 per cent for men.
The gap between the science and the marketing has drawn concern from medical experts. A fast-growing black market for peptides, which are amino acids used for anti-ageing and cosmetic purposes, has been flagged as a potential health risk. Meanwhile, a clinic in Switzerland has identified what it terms "longevity fixation syndrome," describing a pattern of behaviour comparable to compulsive addiction, in which the pursuit of a longer life begins to erode the quality of the life being lived.
The irony is not lost on researchers. Chronic social isolation is well established as a significant risk factor for premature mortality, with effects comparable to those of obesity or smoking. Yet meaningful human connection rarely features in the elaborate health protocols of longevity enthusiasts.
For now, the consensus among scientists remains clear: genetics play a substantial role in how long we live, and the fundamentals of good health, including regular movement, balanced nutrition, quality sleep, and strong social relationships, remain the most evidence-based path to healthy ageing.
