Yeah, me neither.
And telling the difference between human poo and animal poo doesn't get any much easier.
We are all animals, all excrete, all age, all die, all decompose.
Yeah, we humans do think and dream (more accurately, we humans think and dream more than do other animals) but it doesn't seem to have increased our evolutionary luck.
No dumb critter ever came up with a way to mutually assure their species would all instantly die in a nuclear war.
Cleanliness and purity, elegance, beauty, symmetry, equilibrium are all just concepts the old religions and the new religion (Science) use to convince us that the religiously pure and the civilized don't really poop and don't stink, don't age, die and decompose.
The sight and smell of poop and fungoid growths always make that sort highly uneasy or even irrationally angry, because those sights and smells remind them that our mental defences are just that : mental --- totally unable to arrest the inevitable physical processes of our bodies.
And here is where our ability to think hurts and doesn't help : the animals simply poop and move on.
We humans agonize about it, deny it and even organize mass killings of "stinky" Jews, Gypsies, Blacks and Spics around it....
