To further complicate matters, different fields of work have different optimal working styles/cycles as well.
I did some very physical seasonal work for about a decade where most of us would work about 3 months of the year, very intensely. After years of experimentation, the boss of the finest company in this industry figured out that a 3 day on, 1 day off cycle worked best for productivity and morale. This cycle gave everyone a chance to rest and recover from the athletic level of physical labour.
It was really interesting to step out of a 7 day week and into this 4 day cycle every year.
