I've seen many people around me with knee replacements, and I do not want that for myself.
I walk two miles per day. I would not run for this reason.
Studies increasingly show that running is not bad for your knees and runners in fact have some of the strongest healthiest knees around. User proper form, replace your shoes regularly, don’t train for the olympics, and running will be just fine for your joints.
> Studies have shown that recreational runners have a knee and hip osteoarthritis (OA) prevalence that is three times lower than that of sedentary non-runners. Competitive runners showed an even more impressive four-fold reduction in knee and hip OA prevalence. These results are due to the fact that regular running strengthens the muscles around the knee joint and supports overall joint health. Running also plays a vital role in maintaining healthy cartilage and bone density, which are crucial for knee function.

No. Every exercise regime must include a ramp up period. If I started training like an olympian tomorrow I'd be in the hospital by next week. Same thing if a couch potato tried to insta jump into my workout routine.
My contention is with people who don't even try running because they're worried about a hypothetical injury 30 years later.
You can also adjust your training volume if it becomes a problem. For example I got an achilles injury because it turns out 3 marathons in 1 year was too many and I needed to put more focus on recovery.
Caused by running too much ?
Every sport is detrimental at _very high_ level but I think you have a faaaat margin before running becomes an issue, most people are much closer to "undertraining" than "overtraining"
If you learn to run without heel striking (I don't even know how people can run like that but I see it all the time, no wonder it hurts your knees) and don't run on hard surfaces you can run a marathon a week and I doubt you'd ever develop any issues

“Adding an incline is a great way to increase the challenge for your cardiovascular system and get the same kind of benefits that you can get from jogging or running without the same amount of wear and tear on your knees,” says Tyler Spraul, a Certified Strength and Conditioning Specialist and the Head Trainer at Exercise.com.
