"You'll Do More Before 9 AM..."

Listening to the radio this morning in the car I heard a recruiting advertisement for the the US Army. The tag line at the end promised, "You'll do more in a few years than most people do in a  lifetime."  That caught my attention because when I was growing up in the early 1980s that tag line went slightly differently.  It used to say, "You'll do more before 9 AM than most people do all day."  


Even as a teenager I thought that was an unusual point of emphasis when trying to recruit high school kids to join the military. I wonder if it says anything about changing attitudes among 18-20 year olds today that this tag line has now been revised in this way.
