From 20 to 30 if a man live right,
its once in the morning and twice at night.
From 30 to 40 if he still lives right,
he missing a morning and sometimes a night.
From 40 to 50, its just now and then.
From 50 to 60, its heavens knows when.
From 60 to 70 he's slightly declined,
but don't let him kid you, its STILL on his mind!
