I'm talking about remembering to pay attention to getting enough water.
Water is often the afterthought nutrient.
I learned the hard way just how important water was to my body. The temperature went up as we hiked down into the desert. Halfway through the fifth day, we moved into daily temperatures of 95 degrees. Before going to bed that night, I drank almost one gallon of Kool-Aid myself. The product of that walk was a tiny trickle of dark urine.
