PERUVIAN COLD SHOWERS
Here in Arequipa Solar Energy is the popular craze, and most Hotels have Solar heated water, what this means is everyone gets a cold shower. I am always amazed at the level of abuse that can be handed out, the hotel I am in has a 5 gallon electric hot water heater, and then is augmented by solar heat, what this means is in the morning with 15 units you have a cold shower after the dark of night and one person takes a shower, and in the late afternoon you can get luke warm shower. At 23-2500 meters or something like that above sea level, trust me you need hot showers.
On the other hand the girls here are a lot better looking and warmer than the girls in Asia, so maybe this is needed.
