Excessive Laughter Laughing for laughter's sake is just an escape. Jokes alone don't equal happiness, and too much laughter gives an artificial feeling of joy. That's because you got worked up high, but it wasn't real. And the reality always comes back. Silliness, too, is often a sign of running from the realities of life.
Life is serious business, and frivolity destroys meaning.
That's why excessive laughter and misplaced levity can lead to immoral behavior. Dirty and ethnic jokes are especially problematic. That means to say, don't be disrespectful by laughing at serious subjects. Never poke fun at idealism, on the need to help save humanity. You've injected a destructive energy into society.
