It seems to me that they tweaked something.

Or maybe they just don't have any system for consequences and effects.

Right now, I'm trying to determine all the causes of death, and here's what I've come up with so far:

Getting lost in the wilderness - good environment
Cancer - bad environment
God's will - high religiosity (there's a 100% correlation here, just like with those who get lost).
Heart disease - obesity
Sunburn - high nudity
Murders - low law enforcement rate + some other factor
War - high self-defense rate
Disappearances - POSSIBLY, high corruption rate
Exposure - not sure, maybe due to toxicity.
