Wait a minute, since I was born and raised in the Eastern time zone my body temperature will drop according to the Eastern Time zone morning no matter where I live?
Personally I'd rather work third shift and sleep days. I've done it for stretches of a few months to a couple years on 6 or 7 different occasions. Never had a bit of trouble adjusting to it. Matter of fact, I prefer it. I've worked third with people that couldn't stay awake if their lives depended on it, though.
