Saving water

My six-year old son told me earnestly yesterday that I should take showers instead of baths, since a bath used twice as much water as a shower. In theory I agree, except that since I have MS my balance is shot and taking a real shower is a somewhat worrying experience, let alone standing in a slippery bathtub with one arm raised like some kind of demented ape. Having said that, for just getting wet for the sake of getting clean I completely agree, however nothing beats the sybaritic experience of just laying in a bath of hot water, reading a good book (Survivor by Chuck Palahniuk). Given our aquatic origins I would think that this is a natural state for us and so far more relaxing than even being supine on the sofa. While a bath takes twice as much water as a shower in my son's example, an hour-long shower would doubtlessly use more water and allow for less reading (I believe showers over a certain length of time are referred to as "waterboarding" in some countries). So while I have doubtless used more water than I should, my general sense of wellbeing has improved in a way incomparable with the amount of water wasted. Now, must turn off more lights to make my carbon footprint smaller again...
