The crew gets word to the toolpusher, who takes a quick look and tells the derrickman to call 911. The pusher carries Max into the shade and tells a crew member to get the water jug off the rig floor and bring it down fast. The pusher does all he can to cool Max off, for he knows that Max is suffering from heat stroke. By the time the medivac helicopter arrives, Max is in a deep coma. The medical technicians rush him to the hospital, where, after prolonged treatment, Max survives.
Heat stroke can kill a lot of brain cells.
The preceding story did not really happen, at least not exactly the way I related it. But I want to make a couple of points. One is that if you work outside in a hot climate, be aware of heat stroke. Heat stroke is life threatening and, if it doesn't kill you, it can cause serious injury. Heat exhaustion often precedes heat stroke.
