You can always be bummed out about ageing. It's OK to mourn the loss of an identity that you'd grown into. I'm getting my first grey hairs in, and its not easy seeing that in the mirror. It brings a lot of complicated feelings. Humanity has spent our entire existence grappling with the finality of time.

But my wife? She loves those grey hairs. She thinks they make me look even sexier. Time is unrelenting, and brutal. But love doesn't care about time. Love, and joy, and friendship and kindness... These things will happen at every point in your life, if you let them.
