I am pretty sure that is completely false, from what I have read of the early space program, it sounds like it had a way of devouring lives.

"The Apollo 11 crew calculated they spent 2000 hours in simulators between their selection in January and their flight in July 1969." http://history.nasa.gov/SP-350/ch-8-3.html

And the book makes numerous references to others at NASA working long hours too.

"Apollo had become intimately interwoven in the fabric of the waking hours of my life and often caused the remaining hours to be fewer than they should have been." http://history.nasa.gov/SP-350/ch-7-1.html

"I'd be checking on alertness, especially among men who had been working long hours. Were they fatigued? Were they concentrating on the dials? Was there any unnecessary chit-chat going on?" http://history.nasa.gov/SP-350/ch-6-3.html
