When your children are right

My son gave me some good advice recently. He said that I should tone down my indignant attitude. 

For years I was like a ticking time bomb and now with no filter I can get abrasive with stupid and ignorant people which serves no purpose other than elevate my blood pressure. 

He is right of course and as I work my way increasingly into calm territory I need to put down the weapons I developed over my lifetime. I still need self defense, but I don't need to overdo it.
