well this is just an idea so here it goes...

it should be called status or just be a symbol of a human body outline and it should tell you your injury status and if you've got any addictions to (herbs/drugs/plants) that's where some new resources come in like tobacco plant and any other thing like it *good or bad* they can have a good effect but get addictive and then have a bad effect.
It can also show any effects for foods like benefits or cons to stop people ONLY getting fish and to start cooking (when it's fully implemented) and if any special weapons have any good effects. This is not trying to bring drugs in but to have more of a variety.
