Drinking urine is a good alternative wherever water is scarce. It not only satisfies the need for liquid, but also actually keeps the body healthy. Some time ago there was an earthquake in Egypt. A survivor was pulled out of the rubble in Cairo after being trapped for three days. The man had kept himself alive by, among other things, drinking his own urine and he was in excellent condition. I heard another story about a man who kept himself alive with his own urine for a week in a collapsed mine. At the time of his rescue, he looked fine and was in extraordinary health.
