Who here really has the time to stand, think and waste in the shower?

Me, my village gets its water from a spring in the mountains above that provides many times what we consume. The energy to heat it comes exclusively from photovoltaics and solar thermal panels between April and October. Standing under the hot shower is literally free for me in those months.

Rest of the year, eh, okay I either pay for electricity or stuff four more pieces of wood into the stove for half an hour worth of hot shower water, so, basically free as well.
