AMPUTATION

HUNGRY?

Sometimes you are hungry, or you have an infected limb, or you are bleeding and have no rag or bandage with you but you have a Knife (or other sharp melee weapon or bone) with you, if that's the case, do not hesitate cut off that limb and your problem is solved!  Open the context menu on the Knife and select "amputate". Just don't cut your head or chest off, that is instant death!

EXTRA TIP: You can amputate limbs and body parts of corpses too, and sell/eat/use them!
