I believe I once read that a male Urangutang is actually 4-5 times stronger than an male human and is literally capable of tearing one limb from limb.
That's what I've heard as well. Even more, I've read that a grown-up male gorilla (the big guys) could, with some training, easily lift a
tonne - 1000 kg, about 2200 lbs. Fortunately, orang-utans and gorillas are very peacefull.
And we wondered why Grimgor is S5...
Could one of the medics around here perhaps explain why apes beat humans in strength hands down, even though they have a comparable amount of muscles? I'd be very interested in the explanation.
