This is because when times get really bad, as they did when the Soviet Union collapsed, lots of people just completely lose it. Men, especially. Successful, middle-aged men, breadwinners, bastions of society, turn out to be especially vulnerable. And when they just completely lose it, they become very tedious company. My hope is that some amount of preparation, psychological and otherwise, can make them a lot less fragile, and a bit more useful, and generally less of a burden.
