Why is wisdom wasted on the old?

I hear old people complain that youth is wasted on the young. It's probably true. I'm in the prime of my life (oh God, that's scary) and I normally just sit around.

Yep.

Just sittin around.

Looking at the computer screen.

Eating used-to-be-frozen pizzas. (because, really, who eats frozen pizza?)

I don't know that anyone has asked why wisdom is wasted on the old. Some old people just sit around without their youth, while us youngsters are running around like idiots because we don't know any better.

You give me your wisdom, and I'll use my youth. Heck, if I had your wisdom, I probably would use my youth.

Full circle.
