In hindsight, naked gardening may have spared me from the near death heat stroke I had fun with today. Took a tree down with the chainsaw and was running its branches through the mulcher/chipper when I realized something wasn't quite right. Got dizzy/lightheaded, my heart was racing, etc. Barely made it inside. My eyeballs went completely red. Almost blacked out a couple times. Ended up drinking a couple gallons of water/gatorade and sitting in a cold shower for about an hour before I could make it to bed and pass out for another hour. I was an idiot - it's friggin hot out there.
Of course, naked gardening would have meant even more spider / ant bites. Got a few of those today.
