It's also news I've taken in my stride – given I am a person who walks wherever I can, for better or, more often, worse. To and from work, across the city to a Soho hotel to interview a C-list actor from an ITV period drama, back from nights out in the small hours ... I'll walk them all, and fairly nippily.
Does my insistence on never agreeing to get a taxi or bus after a long day regularly enrage anybody in my company? Absolutely. Do I arrive at many professional and social events unacceptably sweaty? Oh, you bet.
This is turning into a brag, but you too would feel good about yourself if an academic study had shown you'll have the body of a 30-year-old by the time you're 46. I'm only 30 now, actually, so I suppose this is it for a while.
You don't need to look far to find evidence of the health benefits of walking. In 2019, the British Journal of Sports Medicine found that a brisk walk once a week is enough to significantly reduce the chances of an early death.
In the same year, the American Society for Clinical Oncology published a study showing how people diagnosed with breast cancer who walk 180 minutes a week were roughly half as likely to die from the disease, compared to those who didn't, over an eight-year period.
Also Stateside, this year a study found brisk walking improves brain health and thinking in ageing people with memory impairments. And the Stroke Association recommends a daily 30-minute stroll to help reduce the risk of suffering a stroke by up to 27 per cent. But making the most of it requires stepping up the pace.
"These days we are more sedentary but living longer, so we are learning properly about walking," says Joanna Hall, founder of fitness programme WalkActive. "You can save yourself a gym membership if you do it right, and get the fresh air and social benefits at the same time. Quality is more important than quantity, though, so you don't want an amble or a stomp, but you do want to be quick."
To get the most from a walk, Hall recommends forgetting the arms pumping, hip-wiggling style of power walking, made popular in the 1990s, and going back to basics.
"Doing it like that causes masses of tension in the body, and puts greater stress on the lower back, with an unnaturally short stride. Instead it's best to push off with the back foot, keep your head directly above your spine, and focus on briskness."
How do you know if you're being brisk? "One, you should be slightly out of breath. If you're ambling along, occasionally stopping to pick up your dog's poo, you're not working up any obvious effort – and that's not enough.
"Two, if you're walking with someone, or even on the phone, you shouldn't be able to have a normal conversation. It should be breathy, with neither person able to easily interrupt. And thirdly, look at your cadence. At a minimum, aim for 120 strides per minute, which roughly matches the rhythm of your heart."
Abraham Lincoln famously said of walking: "I may walk slowly but I never walk backward." Oh Abe. So honest, and yet so naive. Now, the science is clear: pick up the pace and you could roll back the clock.
