Youth is a gift of nature, but age is a work of art. I don't remember who said it, but I do remember reading it somewhere. And so many a man adore youth, for youth is beauty. So what's with beauty and youth if they lack the wisdom? Martin Luther King had said that it would be a good thing if young people were wise, and old people were strong, but God has arranged things better.
People always say that age is nothing but a number. But age is other things too. It is wisdom, if one has lived one's life properly. It is experience and knowledge. And it is getting to know all the ways the world turns, so that if you cannot turn the world the way you want, you can at least get out of the way so you won't get run over.
