I have heard a lot of stories of people getting stubborn/grumpy as they get older. And it seems that men tend to be worse. I haven't experienced it first hand but may soon will. There's school to teach mischievous kids but is there a way/place that educates older folks to behave? Just wondering, "the older the wiser", how true is that?

I am jotting this down. In case one day in the future I become one grouchy old man, slap me in my face and show this to me.
