Try working rotating shifts.
I lasted about 3 years at Kaiser Aluminum (mid 70's) with a similar schedule, which they called a 21 day turn.
Week 1: Swing shift, 7 days straight then 2 days off.
Week 2: Day shift, 7 days straight then 2 days off.
Week 3: Graveyard shift for 7 days then 5 days off.
Repeat for 5 years then you got 10 weeks paid time off to clear all the toxins from your body. It was brutally hard work that paid pretty well.

Those were eight hour days right? We worked an eight hour, three shift per day schedule for a while before the current 12hr schedule.
