“Gross well says that children are young because they play, and not vice versa; and he might have added, men grow old because they stop playing, and not conversely, for play is, at bottom, growth, and at the top of the intellectual scale it is the eternal type of research from sheer love of truth.”

“People don't quit playing because they grow old. They grow old because they quit playing.”

“We don't stop playing because we grow old; we grow old because we stop playing.”

“We do not stop playing because we grow old, we grow old because we stop playing!”

“You don't stop playing because you grow old. You grow old because you stop playing. ”

“Men do not quit playing because they grow old; they grow old because they quit playing.”

“Stop playing hard to get""I'm hard to get. I'm not playing.”
