Getting old might not be something that’s yet to cross your mind. Butageingis inevitably going to get the better of usone day, so it’s something I’m sure we’d all like control. It would be great to have a long, healthy and happy life, and that’s why scientists are constantly seeking out evidence that will show us what we need to do to achieve longevity.

We all know that regular exercise is good for us. In recent years we’ve been told to aim to walk 10,000 steps a day to remain healthy, although other advice to do three brisk10-minute walks a day is thought to be even more effective. But the latest piece of research might puta spring in your stepif you’re someone who walks at afast pace. That’s because, according to scientists, the speed at which people walk in their 40s is a sign of how much theirbrains, as well as their bodies, are ageing.

The BBC’s Philippa Roxby writes that tests on 1,000 people from New Zealand born in the 1970s found that slower walkerstended to show signs of “accelerated ageing“. Their lungs, teeth and immune systemswere in worse shapethan those who walked faster. And to add insult to injury, the study found not only did slower walkers’ bodies age more quickly, their faces looked older and they had smaller brains. Professor Terrie E Moffitt, lead author of the study, told the BBC: “[it] found that a slow walk is a problem sign decades before old age.”

This might be seen asa wake-up callfor people with a slower gaitwho might feel it’s time to work outand get fitter. But it might be too late; researchers writing in JAMA Network Open say they were able to predict the walking speed of 45-year-olds using the results of intelligence, language and motor skills tests from when they were aged three. They also suggest that even in early life, there are signs showing which people will go on to have a healthier life.
