I am reminded - perhaps unfairly - of a tale from my Army days.
During basic training, it was announced that religious individuals - Jewish or Muslim, we had both - would get a break from activities, including morning PT, for the purpose of attending prayer.
As basic training wound on, more and more members of the platoon found religion. I believe as many as 20 men out of a 60-man platoon would be absent from morning PT in the last week.
