Spanking works because it's gratifying - when a parent wants to spank its cause they are filled with an energy anxiety stress and spanking is like exercising it out and spanking/slamming a lid on the anxiety - the recipient doesn't feel better and is in fact now filled with the parents anxiety along with the issue whatever it was but now they have a lid on that and their own anxiety they have learned better than to open it - in essence learned to 'not' communicate but to bottle it up and work it out with exercisers like yelling, spanking, blaming, drinking, running, fighting, working etc

The point is that those are all calorie burners
and burning calories and exercising are both good
therefor spanking must be good.
