I can see it all, now, Wingin'it.

Some would be running with their clubs for the cave for more supply; the shy, quiet artists (not a Van Gogh, Michaelangelo, Da Vinci, etc., just the homemaker who is an artist and creates lovely floral paintings) fleeing as fast as possible from the cave dwellers and trying to find some place clean, well-lighted, and quiet (as Ernest Hemingway would say).

I'd be scared to death to be with the 93% of bipolar patients who never seek help for their illness and never take any prescribed medication for the volcanic explosions or tear-flooding hours.

My first question in such a case might be to ask the cave man or cave woman standing next to me, "are you taking any medications for help?". Then, we might talk friendship if the answer is "yes". Otherwise, it would probably be every one for himself/ herself; forget the togetherness of loving personalities; it would genuinely be the survival of the fittest. And in such a case,the "fittest" would always be the one who carried the heaviest, strongest club.

As "Dubble Monkey" would say, it would probably be a free-for-all. He's really a very sharp dude on this forum, Wingin'it. You should get to know him.

God help us if we ever have an apocalypse of the type imagined on this thread by several. There would be no need for the 7 plagues of the Bible.
