What if the poop hits the air recirculation device?

You could have asked that question 50 years ago.  The threat of nuclear war has existed at least that long.

Today's troubles are compounding that, which has never gone away.  Today's troubles are within, or so it seems.  That can change pretty fast, for nature abhors a vacuum.  Some entity or entities will rush in and fill the gap that the US leaves behind.  Then the troubles can no longer be denied.  Until then, what?

You can just go on living like everything is normal until it isn't anymore.  That doesn't mean to go into denial that there's problems.  No, but you cannot let your life be determined or dominated by this fear.  Live the best you can.  That's all anybody can do, and has always been so.  The end of the world has always seemed near.

"Sufficient unto the day is the evil thereof."

Upon a little reflection, this little ditty may seem too good to be true.

In that case, screw you then.
