Neat study, but I always chuckle at these, because has there ever been verified science that shows exercise is unhealthy? (besides overtraining)
The general consensus should just be exercising is good for you, that's it, done.

Yes, the extremes of endurance have certainly been shown to have a negative effect on heart health, and possibly also colon health, but the amount of exercise required to get into the danger zone here is so high almost no one that isn't a competitive athlete would achieve it. (Although, amateur marathon runners might.)
But I agree, it would be better if everyone exercised!
We know that exercise is good for us, but studying it is how we better understand the different ways it is beneficial for us in a controlled setting.
I see these comments online a lot, just because something might be common knowledge, doesn't mean we fully understand it, nor should be stop studying it.
