Another thing that can lead to "choking" - or at least not performing correctly - exhaution

I can remember a couple years ago, sitting at a friends place, TRYING to coil a roll of coax cable, a messing up 2-3 times in of, 5 minutes.

Didn't help that I had been up almost 60 straight hours (all 3 of us had), that in those 60 hours, the temps ranged from a LOW of about 90 to 102, and we were rushing to get some gear now and inside before a thunderstorm hit (we could hear and see it coming).

I think I got it right on the 4th or 5th try, walked inside his house, laid down on the floor, and was out like a light bulb in about 5 seconds
