After chopping wood for about two hours on a hot
but breezy afternoon, Mr. X stumbled into the house and
then fainted. His t-shirt was wringing wet with
perspiration, and his pulse was faint and rapid. Was he
suffering from heat stroke or heat exhaustion? Explain
your reasoning, and note what you should do to help Mr. X
recover.
