What’s my biological age and how do I calculate it?

You’ve probably heard the phrase “You’re only as old as you feel”, but what if there’s a science behind that statement? That’s the idea behind biological age, a concept that’s starting to make its way around various health circles, even though it’s not yet fully standardised. Unlike your chronological age (the number of candles on your birthday cake), your biological age reflects how your body is ageing on the inside.

What is the meaning of longevity?

Ask five different experts what longevity means and you’ll get five different answers. To a fitness fanatic, it might mean hacking your biology to reach 120. To your GP, it might mean avoiding a heart attack in your 60s. To the average person? Probably just being well enough to enjoy old age or to live long and well.

The healthspan gap explained: bridging the divide between longevity and healthy living

Many people spend the final years of their lives in poor health. This is the healthspan gap - the difference between how long we live (our lifespan) and the number of years we live in good health (our healthspan).¹

What’s the difference between healthspan and lifespan?

When we talk about living longer, it's important to understand the terms 'lifespan' and 'healthspan'. But what's the difference, and why does it matter? Simply put, lifespan is how many years you live, while healthspan is about how many of those years you live in good health, free from significant illnesses.¹

What your healthspan is and why it matters now more than ever

From Oscar Wilde to Doctor Who, we’re always fascinated by living longer. But a critical question remains: how can we make sure those added years are healthy ones?

How can I extend my healthspan?

We’ve become pretty good at living longer. Thanks to modern medicine, safer environments, and better access to food and clean water, average life expectancy has soared over the past century. But while we’re gaining years, we’re not necessarily gaining healthy years.
