"The aging process has you firmly in its grasp if you never get the urge to throw a snowball."
"Blessed are the young, for they shall inherit the national debt."

"Youth fades; love droops; the leaves of friendship fall; a mother's secret hope outlives them all!"
"Age and youth look upon life from the opposite ends of the telescope; it is exceedingly long, - it is exceedingly short."
