Although water, hot or cold, might be the perfect drink, it holds little appeal for me, and at my age I don't think I shall change. I drink copious quantities of tea and fruit juice though and enjoy a few coffees each day. A few years ago, when I was working, the office went through an obsessive phase of everybody sucking on bottles of water every five minutes because it was supposed to be good for you. The main thing it did was increase the traffic to and from the lavatory all day. The ones who did it showed no amazing health benefits that I could discern, aside from exercising their bladders.
