Yeah, that.
Throw first aid at their feet. Theyll pick it up. I guess
Or sell it to them
shotgun shot to the face and wait for them to reincarnate in a next life 
Should they survive a buckshot in the teeth they [I]were[/I] in great health.
Currently I don’t believe there is a way to check their health unless looking (x or 
at them works but I don’t think it does.
Perhaps this is something the devs should look into.
My idea would be to give them hp ranges.
For exemple: this person looks “healthy” “injured” “agonizing” etc.
