The high that day about 4pm at 94 degrees and less than 50% humidity. Not much to kill someone unless they were well on their way by then.
I recall when a kid my grand mother made the mail man drink a glass of cool water on hot and humid days pre bottled of water days.
Days when people cared about others.
Worked to death?
electrolyte powder and water, and not dehydrating yourself with alcohol or caffeinated drinks when off work.
so sad to hear that apparently this man and others mentioned in comments didnt prepare well for the weather of their job OR stop along the way and get proper liquids to stay hydrated, OR just stop and get themself help!
The few times I had heat exhaustion/dehydration it wasn’t sudden, I could feel I wasn’t ok in advance.
The heat is only one factor. Another is the heavy bag of mail and/or all the heavy lifting. Then, all the overtime hours.
