This morning at church service it was announced that someone who was a friend of a member had died of a heatstroke the day before. This person was only 27 years old.
I came close once, and knew something was wrong when I started getting the nausea. Fortunately I was with someone who drove me to a nearby convenience store where I pounded down a cold Gatorade and a bottle of cold water.
It's that time of the year, and it's only going to get worse before it gets better. Slow down, drink plenty of water, and be careful out there.
