Hey, stone age man used atlatls on Mastodons and Mammoths - maybe hunted 'em to extinction. OTOH, I'm not gonna use one on a grizzly! Or even a black bear.

Well, look at it this way. We're alive right now, so that means either our ancestors were tough enough to take on mastadon with an atlatl or smart enough to let Og give it a try first.

BTW, and it's a pretty strange story, but I actually used one of these things one time. The pictures don't show the most important piece - the thong that holds it to your wrist. You really heave on one of these thingies and it gets a little hard to hold onto.
