Reset Your Healthy Life

As we build on the themes we introduced in our first newsletter, I want to return to a question that sits at the heart of living longer and better: why do we accept decline as inevitable when the evidence says otherwise?

In Episode 4 of the Live Longer Better Podcast, Leslie Kenny and I explore a simple but often overlooked truth - there is no stable adult phase. Much of what we call ageing is driven not by biology alone, but by decades of inactivity. Sitting for 30 or 40 years at work, moving less, and accepting decline as “normal” quietly shapes our future health.

The evidence tells a different story. If people remain active - or become active later in life - they can regain strength, stamina, suppleness and skill, and confidence. We describe this as closing the fitness gap: the distance between your best possible rate of decline and your actual one. That gap can be narrowed at any age.

What stands in the way is rarely your capability. It is ageism, outdated beliefs about what older people should or should not do, and healthcare systems that unintentionally promote deconditioning by discouraging movement.

The core message is simple: the older you are, the more important activity becomes.
