Amen. There is evidence that, other things being relatively equal, people
working rotating shifts have shorter life expectancies and that the faster
the rotation, the shorter the expectancy gets. There also is some evidence
that people working rotating shifts are more likely to get cancer.

My experience: 

6 on, 2 off, 8 hours, rotating to the next later shift: I never, ever got
enough sleep -- for 2 years.

6 on, 2 off, 12 hours, straight mids, no rotation: much less bad. 

5 on, 2 off, 8 hours, straight mids: quite tolerable.

5 on, 2 off, 8 hours, straight swings (1600-0000): out of phase with the
world.

YMMV; I expect it to.
