No, it's not just "elderly women" ffs! Chimps are killing men in Uganda right now, for just one example. There are numerous stories of Chimps attacking and killing people, mostly men. The average Chimp has 5xs the strength of the average male ffs. You think you can take that on? Hilarious.
I could put links, but it is way too graphic and disturbing, so google it yourself.
Most humans could not "take on" a wild animal, but I think I could fight off a Coyote if it went after my pets or something.
