Meanwhile, with respect to what I'm doing, what do folks think I'm
talking about when I say "it's Difficult"?
I'm not 'oblivious'.
It's just that there's needless Savagery out-there, 'just' because
folks don't understand how nervous systems process information.
It's no contest.
With respect to the rest, I 'take-it-on-the-chin', as best I can.
