Hi Ox,
The "T" shirt is tucked it. When the "blouse" is worn it is not tucked in. Funny thing is it was typically worn with the sleeves down. This was to keep from getting burnt. Also, if you sweat inside that shirt, it felt cooler. Hard to explain.
I think the body temp will rise, mainly in cases of heat stroke or heat exhausten. Drinking plenty of water and staying out of the sun as much as possible helps prevent this.
No cold showers (they were all too hot) no kegs, some women co-workers (nuff said

The camels came by nightly to watch us, the humans. I'm not kidding. We must have been a sight in our cage!
The guy who did the door did a good job. He did about a dozen while we were there. Difference was, his held up. He did our tent at tent city and didn't even live there. His civilian job is a prison guard, His military job is survival shop (parachutes etc...)
We don't mind doing what we do. Don't even expect much thanks for it. Plenty of others have done the same or more with little acknoweledgement. Albeit it is nice to get a thanks now and again.
God Bless,
jerry
