Guys & Gals, I would urge all of us to be very, very careful of this heat. It is nothing to play around with. I really feel for those who have to work in it.
If at all possible, take breaks, drink LOTS of water. Heat exhaustion is bad enough but heat stroke can and will kill you. If you start feeling bad, get in the shade/cool. Don't try to "man up and take it". That's a good way to end up having your kin deciding who gets what bow now that you will no longer need them.
