There's a reason why for centuries exercise has been the go-to prescription for vitality. Yes, exercise improves blood flow. Yes, it improves lung and heart health. Yes, it gives us bigger, stronger muscles.
But more than any that-and indeed, what is responsible for much of that-is a simple thing that happens at a much smaller scale: the cellular scale. Those who exercise have longer Telomeres.
Those with Just half an hour of jogging five days a week have telomeres that appear to be nearly a decade younger than those who lead a sedentary lifestyle.
There’s no way around this. We all need to be pushing ourselves specially as we get older. Yet only 10% of people over 65 exercise. Get your parents to do some form of exercise. And they will only do if you care for yourself. Start yourself first.
