I'll have to spring that one on the wife. "I'm practicing my survival napping skills." I'm quite sure the boss at work won't buy it. :-)

Conserving energy is very important so forcing yourself to rest at appropriate times would be good strategy.

I've thought about this a bit in the context of my long walk home in the event of EMP. I've concluded that I'd probably wind up walking during the dark hours and sleeping/resting during the day for the simple reason of staying warm. Moving during the coldest hours of the day (night) means I wouldn't need to be carrying polar level insulation to survive the coldest hours while also being inactive. Resting during the heat of the summer day is also an important natural strategy.

The hard part would be forcing yourself to calm down and do it rather than nervously doing something because you feel you must.
