Youth is (not always) wasted on the young...

Some may only know illness, growing old and death;
Many are oblivious to any (or all) of them.
Some are too distracted from aging and death by their own or others illness.
Some who are aging are trying to avoid death.
Those who are dying need not consider aging nor illness any longer.

While we are aging, ill or not, consider death;
It will keep us joyous, happy and peaceful.
Bring these qualities to all of your relationships, nay, everyone you meet.
