So? I spent 31 years working rotating killer shifts I survived. 8 hour backward rotations,(killers!) then 8 hrs forward rotation, then killer 12 hr shifts 6AM-6 PM, then 6 PM to 6 AM. still alive at 79 years of age. Retired 17 years ago, still cannot get to sleep before 12 Midnight but wake up at 5 AM, 6 AM, 7 AM every morning, all my old wake up times going back to 1970 when I worked in a steel fabrication shop before rotating shifts.
The best shifts I ever had came when I was USAF working on a Navy Base. The brass were free to choose which service regulations to use, so chose the most permissive.
We worked 12 hour shifts. Two shifts days, 7 am - 7 pm. 24 hours off. Two shifts nights, 7 pm - 7 am. 48 hours off, then back to day shift. The best of all possible shifts in the military.
A year of that, and since I was the only one who had a clue about the brand new communications computer, the Captain in charge of coms offered me a 4 year controlled tour.
I worked from home for years, editing and sometimes writing books for clients who paid me more than I made at publishing company. And worked my dainty ladylike arse off, sometimes getting zero sleep.
After several years, I was just too very tired to do it. Moved to Florida and spent a lot of time catching up on sleep. And fun. And life in general.
That worked, I’ll be 90 next month, which no one who looks at me believes. Weigh 112, great posture, try to talke a long walk every day. Eat mostly organic foods, Sleep long hours, and my cat does too. Don’t live in FL now, moved to Spokane to be closer to my daughter.
Yes, I worked high stress long hours in the mortgage industry for many years then 17 years owning my own mortgage broker firm. Even when I wasn’t at the office I was on call for clients 24/7. Stress up the wazoo. Now I’m retired and still in good shape enjoying life.
“but wake up at...all my old wake up times.”
It’s crazy how those patterns become biologically embedded. Any night where I get a reasonable 6-8 hours of sleep, and don’t have to set an alarm, I’ll wake up naturally within 1-2 minutes of the normal time.
Gotta admire your endurance working those shifts. Lots of kids today find it difficult to work a regular 8 hour shift during daylight hours.
