i dont see how it's sub-optimal to shit yourself when you're exerting all your effort. not that it's optimal. it just doesnt matter. if you're running for your life, who cares. you'll wash later.

    Lighten the load, expel waste, free up mental and physical resources from holding it, and deter a predator? Sounds pretty dang optimal to me!

    and it's not like predators cant smell where you've gone, even without this. humans had to have become used to not being able to smell all that well while pretty much everything around them could smell very well
