It's a hard thing to age a character because you can't really suddenly give someone gray hair.

Gray hair is God's graffiti.

For guys, growing older is fine. Gray hair and wrinkles aren't considered a bad thing.

I've had completely gray hair since, like, 30.

There is only one cure for gray hair. It was invented by a Frenchman. It is called the guillotine.

I'm enjoying the aging process and the gray hair and the wrinkles.
