In reply to Gfoz:
Chimps, gorillaz, etc, are just so sick strong compared to humans, you wouldn't believe it. An enraged female chimp was once recorded as pulling on a strain guage handle and registering over 600lb (I think this is mentioned in the Guiness Book of Records, or something). I used to be pretty good at deadlifting (OK, I'm sorry) and once managed 440lb. That was, like, eyeballs popping out AND with two hands STRAPPED to the bar, and done pretty slowly. It's not fair. We're so genetically close to them, as well. Makes you wonder what tweaking a few genes will do. Perhaps, one day, chimps and humans will be able to communicate. Imagine being able to say to a chimp 'do you fancy coming down the plantation and working on that new problem?' Then, later, 'yeah, if you rock over on your right before you hit the smear with your left foot and release the right toe hook, I think you've got it.' I bet they could positively scamper up something like Careless Torque, which would end up being renamed 'Staight Banana'. There would be a separate grading scale for each species, as I bet gibbons and smaller monkeys would just be bloody brilliant, whereas your silverback, on the other hand, may be a bit closer to your average Joe (Young). Oh, yeah, and of course, they can use their feet like we use our hands.
