‘WHEN it comes to exercise, what everyone wants to know is, “how little can I do?”,’ says Professor Bill Kraus, a cardiologist at Duke University in North Carolina.

And the answer is... to reduce your chances of dying early by almost a third (30 per cent), you only have to walk a mile every day (that’s around 2,000 steps).

There. It doesn’t matter if... See more

More than 20 large-scale studies, tracking millions of people over many years, have all reported the same thing: the shorter someone sleeps, the shorter their life.

Caloric restriction – cutting back what we eat – has the same effect. Dr Longo has studied caloric restriction for more than three decades and is clear that, with the right nutrition and fasting, we can optimise our chances of staying fully functional into our 90s, 100s and beyond. The brilliant news is you don’t have to fast for long or cut back... See more

More than half of UK adults (51 per cent) aren’t getting enough sleep, with a third struggling with insomnia and 74 per cent reporting a decline in the quality of sleep over the past year.

The reason this works mathematically is that both US and UK national guidelines recommend 150 minutes of moderate intensity exercise a week, which in walking terms ‘is about 3 miles an hour’.

‘Every mile is around 2,000 steps,’ says Dr Kraus. ‘So if we are telling people to do two and a half hours of moderate intensity physical activity a week at 3... See more

The average night’s sleep in the UK is six hours 49 minutes – and the consequences of regularly getting less than seven hours sleep are enough to give anyone nightmares.

In fact, along with cardio and resistance exercise (any form of weight-bearing exercise) there is a third form of workout we should all be doing called ‘neuromotor exercise’.

Neuromotor exercise is anything that requires you to move while also having to think, and it’s extremely good for our brains. Yoga, Pilates and tai chi come under this... See more

One of the first experts I turned to was Dr Valter Longo, professor of gerontology and biological sciences and director of the University of Southern California Longevity Institute in LA. He believes the key to anti-ageing lies in fasting.

When we restrict what we eat, and therefore limit the energy coming into our body, we force our cells to eat... See more
