How can I stop a sim from die-ing from laughter?

Yes, I don’t like that sims die from hysteria, I think it’s dumb. I would love to have a comedian, but am always afraid they will die of that. Like someone else mentioned I usually send them to bed, and I don’t let my sims tell too many jokes. I don’t like that they can die of embarrassment either. Neither of these deaths make sense. They should have just made strong negative moodlets for each. I can understand them dying from extreme anger.
