notice the word "generally".
I was not trying to compare one species with another. It has more to do within a species.
Shorter/smaller/thinner humans tend to (on average) live longer than bigger/taller/wider humans.
I remember going to my best friends doctor's appointments and his Nephrologist told us that he had a lot of dialysis patients (people who's kidney's are not functioning well enough, many not at all) that were body builders. He said that constant over stress on the organs are not good for the organs. When working out, if we need to make big grunting noises while working out, that we are probably over doing it and over the long term, causing damage to organs. He said it was not necessary to do that in order to build muscle and/or get a good workout. He recommended less weight and more reps as being the way to go. He did not say that was the only reason why they were there. But he said it was a contributing factor. He saw it too often for it to not be considered a factor.
A good example of what the doctor was talking about is Vic's Natural:https://www.youtube.com/user/vicsnatural
And as for a bad example...there are a ton of them. I think that Scott Herman has gotten way out of hand and what he is doing now has nothing to do with health. He is just challenging himself to get bigger and bigger, and to lift more and more.
