This morning I heard the end of the debate on saving human energy on the radio. So I'd like to ask you what you say. When you say you drink hot tap water (which makes me quite disgusted to get water from the juice and pour lukewarm water on it) then the body no longer has to heat the water and the saved energy can be used differently. It is said that this way you can save a lot of energy per day. What do you think about it?
