I've worked shift work all my life. Rostered minimum 48 hrs in 4 days, usually more like 53-55, often 60 in five days, then 3 off, rinse and repeat. Days and nights. My Brother in law works 96 hrs in 8 days - 8 on 8 off. No sleeps on shift. Alert and working the whole time. How do you think a shift, 2 days off, a shift, 2 days off, a shift, 1 day off, a shift, then you're done for a couple of weeks sounds like to him?
What job are we talking about? How much concentration is required and for how long?? How many time zones are you passing through whilst at work?
If you think it's that easy, just do a self experiment trying the QF pattern at home and then try and do a complicated task that requires brain processing. Then remember you have never left your own timezone and have slept in your own bed.
