When I used to work on ships and oil rigs, I could function for 24hrs on a 4 hour nap. But now that I work 12 hour shifts in an office, if I get less than 6 hours, I useless. My wife doesn't understand that my body was trained to wake up and be ready to turn to with any change of light, sound or movement (when a ship stops moving, it means 2 things; you are at the dock or something bad happened). Nothing like going home after a 12 hour shift and having to grocery shop, cook dinner and puts the kids to bed ( goto bed so Dad can goto bed). After all these years of various shift work, I have sleep apnea and a CPAP (which is fantastic)
