Doc. The end

Ah the future, where medicine is so advanced the field of medicine becomes near obsolete. In a world which has the cure for death, whats the use for the medical profession. Hmm, more importantly, how would this affect religion? I would assume a great deal since it appears that some of the believers only do so because of fear of dying, but in a world without death, what do you fear? Never dying? Eternal isolation? Interesting...
