Just as the microscopic world never seems to run out of new strains of bacteria and germs for us to sharpen our immune systems on, so human society never seems to run out of new kinds of crap human behavior for us to deal with. And it never will. We can lament that fact, and we should. We can also embrace the opportunity to sharpen our skills at dealing with crap and maybe develop one our two new tools for next time.
Bleah, right? But we'll be dealing with the Human Crap Condition our whole lives, so we might as well do something with the experience. In some cases it may be the only silver lining we get.
