I found a pretty cool quote from a Dean Koontz book –

“How fortunate I’ve been to live long enough to recognize the subtle but undeniable fading of my youthful stamina and spryness. To hell with those poets who celebrate the beauty and the purity of dying young, all powers intact. I’d be grateful to survive to relish the sweet decrepitude of my eightieth year, or even the delicious weakness of one whose birthday cake is ablaze with a hundred dangerous candles. We are the most alive and the closest to the meaning of our existence when we are most vulnerable, when experience has humbled us and has cured the arrogance which, like a form of deafness, prevents us from hearing the lessons that this world teaches.”

That’s from the book Seize the Night.
