Longevity Needs CUDOS, Not DECAY

In a BMJ opinion on Seamus O’Mahony’s book The Longevity Delusion, Richard Smith offers a pointed critique of the promises surrounding the longevity industry. Investment and attention are growing, but convincing clinical evidence that targeting biological ageing can substantially extend human lifespan remains limited. The piece is an opinion and book discussion, not a new trial or a definitive verdict on every approach to healthy ageing.

What stayed with me was the question of scientific values. Robert Merton’s classical norms, often called CUDOS, ask researchers to share knowledge, apply universal standards, pursue inquiry without personal gain and maintain organised scepticism. Bruce Macfarlane’s contrasting DECAY framework describes pressures toward differentialism, egoism, capitalism and advocacy. It is a critical lens on academic incentives—not a measured claim that all contemporary science has abandoned its principles.

That lens matters in longevity research. Commercial success, striking biomarkers and compelling personal stories can make an intervention look more mature than its evidence. The questions remain: Has a biological signal changed? Does that change improve outcomes people actually experience? Is the result independently reproducible, durable and safe? And who will be able to benefit if it works?

My takeaway

I do not share a pessimistic view of longevity’s future. AI-powered 10P-Health could bring multiomics, continuous monitoring, prediction and personalised prevention into more coherent, lifelong care. It may help us detect risk earlier, select better interventions and learn more rapidly from each person’s health trajectory. Those are reasons for serious research—not permission to promise that we can already slow or stop human ageing.

The path from hope to credible medicine requires transparent methods, independent replication, meaningful healthspan outcomes, long-term safety assessment and fair access. It also requires remembering that social conditions and proven preventive care shape healthy ageing alongside any future breakthrough. Healthspan is an urgent goal; lifespan extension remains an empirical question.
