Ooh, a Life Book sounds neat. It would be fun if for Immortal Dynasties writing was a skill you had to max, instead of Gardening.
What are you guys doing that you're having people die of laughter or embarrassment? I haven't had it happen but I'm wondering if you have to push it.
So far I haven't had any emotion-related death happen. Many people are saying that it just happens randomly for them, so it may be a bug? I don't know. I always experience the emotions in "stages," and I've never had it go higher than the second "stage." (Very Playful, Very Angry, Very Embarrassed.) That normally gives me enough time to calm my sims down.
