Hospital

A place to cure the wounded and sick. Heals the injured or wounded visitors.
Overview
Hospital is a special service building that does not belong to either the entertainment or hygiene categories. Once it is operating, citizens with reduced health will begin seeking treatment on their own.
This makes Hospital an important safety structure for settlements that face frequent accidents or other sources of damage, since it greatly lowers the risk of citizens dying from injuries. It is most useful when placed where injured citizens can reach it quickly, allowing them to recover before their condition becomes fatal.
