Meanwhile, there's stories of sane guys treading water for 2 days. Notably, a difficult act to do whilst raping. But I guess rapefugees make their choice, while sane people make the other one.

Honestly, might make a good litmus test for entrance to civilized society, with some adjustments. "You're on a sinking ship, what do you do?" And just shoot everyone who answers with "rapin' time!", send back almost all the rest, and give more consideration to the ones who try to break off a door to use as a floatation device and give it to others.
