Then my goose is cooked as I spent 31 years working a rotating shift in a power plant.! Retired 13 years ago, and at 74 years of age I still have all my marbles! And can still remember things that happened when I was three years old!
Those were rough rotations! Ten day work shift of 8 hrs, Days, mid nights, evenings.
Then Days, evenings, mid nights. Not so rough.
Then ten years of 12 hrs on, 12 off. A weird rotation of three midnights, then two days, then three days, then two midnights. A killer shift.
I think they were trying to kill us off before we retired.
I know what you mean, but you always settled into a sleep pattern in which you could achieve a good number of hours of sleep, so you are safe.
