[Question] The death formula

I am just asking for content related to the death formula:
How is it calculated (I mean the rate)

I keep having citizens dying even when their activity zone normally have 10%-15% pollution level, and they live in buildings that give 30+ pollution resistance.

Will they just wander to the rubbish incinerators?

Citizens lose HP slowly over time, based on the potency of the pollution around them. They have a passive Heal that allows them to regenerate HP if there is no pollution.

In the future, we will have hospitals that Citizens can attend to recover their health, as well as buildings that reduce pollution in the area.
