A chimp doesn't know how to evade or use it's speed. It has potential to use more, but it's lack of focused power would limit a lot of it's advantages in certain situations. A chimp can run away, but it can't block a punch. Guys can punch through bricks. Guys can kick with incredible force. If they dodged a chimps pummel, a martial artist would have the advantage.
I'll also allow it. It's human nature to use drugs.
No. Guys can break bricks. Not the same thing. Bricks are brittle. Chimps are not.
Chimps are extremely aggressive. I'd prefer to be locked in a cage with a Gorilla than a Chimp.
By far.
