Short note to self: the flesh of zombies

What if zombiism were a disease that made you...

1. Slow as a turtle
2. Afraid of people
3. Tough as granite
4. Naturally long lived
5. Hunted for your flesh as it's believed it can cure diseases when digested

These zombies would eventually look like half-eaten corpses as people would try to chip of pieces of "medicine" from your body.
