Let's talk about laundry!
It seems to me that those collapse-conscious folks who don't ignore the topic of laundry either anticipate a grueling regime of boiling clothes with homemade lye soap, beating clothes on a rock in a stream, or else getting used to living in filth and squalor. Hard as it is to believe for folks who grew up with the convenience of automatic washers and dryers and listening to tales of the bad old days of starch and lye, wringer washers, and/or boiling vats, there is a completely different, totally reasonable tradition of clothes washing that I've observed during the time that I've been in Vietnam.
