Zede's physical development path, was not initially "corpse."
His physical level of talent is quite high in Zion, but not to a particularly exaggerated extent.

Asimov, as a Doctor, realized an important point: 'simply studying medicine cannot save Zion,' relying on the Source Epidemic Area of the Old World is a very good choice to truly extend the human Flame.
