Workers can die suddenly. There is no reason ever given unless it’s a Kenny death but you can sort of imply.
I’m not really sure I’m too comfortable with that idea, it seems unnecessary given the current system already accounts for random deaths.
In my most recent game Sean McFly died at 42. I don’t think I need to see that he died after a bout of cancer, it doesn’t need to be that real for me. Just my two cents.
