Youth 0-70
Age - Every Age
Death 70+
Where is youth? Where is age? Where is death?
Your question was answered long ago by a very wise man named Omar Khayyam. He wrote, "Tis all a chequerboard of nights and days, where Destiny with men for pieces plays."
It's just a game, Rik. We're all just here for the ride. Have fun with yours.
Age is a measurement of years. Youth is a state of mind.
All around you, if you look carefully enough.
Youth is energetic.
Age is when you feel it.
Death is inevitable.
