A couple of times in the past few years I’ve experienced dehydration and, believe me, it is not something I want to repeat. It happened once after I suffered a torn hamstring while cross-country skiing, and another time in the 115-degree heat of an Israeli desert. Both times I experienced dizziness, disorientation, loss of clear vision, and a host of other symptoms. I learned the hard way that water is vital to maintaining my well-being.
