Fine. Why do some people get so mellow when they get old, when they weren't before?

I know of someone who fell off a ladder and hit his head making him nicer in his old age.

susanc, why are you so furious? is it because you’re a young hothead?
;-)

In my grandfather’s case I think it is because he has lived far longer than he ever expected to and he is grateful for every minute he has. I think he finds himself appreciating things that he once may have taken for granted. He is very fond of saying, “you know, it’s the little things.”

That’s not mellow.
That’s senile.

susanc, What age is old to you?
I am nearly 60 and find that I am far more “at peace”, and easy going now, but much more likely to say what I think.

Maybe they’re just tired.

You get a grip on what’s actually important after a while.

Hint: it’s not about being ‘right’ (as in correct, not political).
