In 38 years on this planet, my hot water has never gone out for a few days. Not going to prepare for something that A. Is unlikely to happen and B. Can be worked around by washing my armpits or showering somewhere else.

I have had cold showers abroad, but taking cold showers at home would not have prepared me better for them.

I don't sleep on the floor at home to make camping easier. That would be silly.
