on my local radio station they had a chimp handler (for birthday parties and stuff like that) and he said that a one year old chimp was as strong as he was, and that his older chimps were vastly more powerful than him, and this guy is 275 lbs, he said he had a beery belly, but that he was reasonably powerful too. A full grown adult chimp would quite possibly make ronnie look weak, and a fully grown silverback gorilla would probably make kaz look wimpy. The truth is that when we evolved, we began to rely on our brains instead of our brawn more and more, which is why we look the way we do today, instead of eating bananas and grunting to show dominance....wait...neve rmind
