I was referring more to natural healing ability. In the excerpt that we got from Silence Divine, the main character noted that he had been getting too much sleep recently. That sounds like his natural health is the only thing keeping him healthy. (Or not, in this case.) Since F-Gold is just storage, you should still be able to use it for healing. Alternatively, get filled metalminds to hospitals or doctors. You may get superpowers when you're sick, but they won't do you much good if you're dead. Also, chronic illness healing! Lots of possibilities when you mix magic diseases and magic health storage.
