Every life long runner I know has had a serious knee problem or other injury.
But I think running is higher impact on the body that a lot of of other exercise. You're putting your full body weight on a small area several times a second for many minutes every day.
If that's what you're doing, you're not running correctly. Keep your knees bent so that the shock goes up to your gluts and hips.
I'm not talking about myself and I haven't evaluated the running form of the people I know.
But impact is just force and time and the high pressure is because contact is being made with your foot, which has a small surface area.
You can find hammers that absorb shocks better than others, but ultimately it's driving the nail because of impact and pressure. (Small hammer head striking quickly).
I don't doubt that proper form, correct training, and other interventions can reduce running injuries. But they're the most frequent exercise injuries I've seen personally and they also appear common statistically.
(Of course running is more accessible than, say, jai alai so base rates are higher anyway)
