So, we know that polyjuice changes you more than just superficially - Crabbe and Goyle became girls (hee), Harry's eyesight improved....

Question: What happens if you polyjuice into the form of somebody who has a fatal form of, say, cancer, and you stay in that form for a while? Will the cancer progress in you and kill you? What if it was something like diabetes, and you didn't know? Could you die that way?

Question: What if *you* have cancer (or whatever)? Can you polyjuice into somebody else's shape, and just stay there forever? Would the disease come with you into this new form?

Question: If the polyjuiced person is sick when you take the sample, sick with something not part of the body, something contagious, can you pick up the disease while in their polyjuiced form, and spend an hour coughing? Can you get sick in your own form that way?

Question: What if you use an old sample to polyjuice? One from a decade ago? Would you polyjuice into the form the person was then?

Question: If that's so, couldn't that be used to extend your lifespan? You could polyjuice into your younger self, so long as you had enough samples, couldn't you?

Question: When the fakemoody polyjuiced into Moody, he lost a leg, which then regrew after the polyjuice potion wore off. What if he'd lost a limb while polyjuiced? Would that remain lost in his real form?
