Medical Nanotech

Medical nantoech takes two major forms at TL A. For quite a number of years non-replicating medical assemblers have been used to perform medical intervention in patients. This kind of care includes treatment of ailments and injuries of all types. Many of these types of treatments predate the Grytotech inspired nantotech ban, and so have a long history of acceptance among both the Church and the public.
More revolutionary, and a later technology is the implantation of nanotech factories in the human body with the goal of not only repairing disease and trauma damage, but also in extending life. As might be expected the existence of such technology opened up deep theological and ethical questions.
Is it moral to use such life extending technologies? Obviously manipulation of human fertility processes, without the known side effects of hormone or chemical contraceptives, would cancel out the secular penalties of their use. This does not touch on the obvious moral reasons of the prohibition of contraception, and the negative societal consequences. So as for as for all technology the capability to do something is not a license to do it.
But a complete interdiction on the technology would not be moral either. It is not immoral to extend a human life using surgery or medicine. So implemented in a moral framework the use of anagathic nanotech factories (ANFs) should also be moral.
As might be imagined a technology that can theoretically extend human life indefinitely has real social impact. The limitations of the technique is also important. To be morally justified ANFs must not interfere with fertility or normal procreative process. This limits some of the treatments that can be done, especially in women, and especially during the normal years of child bearing. This has resulted in a societal trend to limit full activation of ANF implants until after the fourth decade of life. Prior to this the standard aging process is allowed to continue, though benefits in disease and trauma repair are typically activated.
ANF implants are basically nanotech factories which create biological assemblers which cooperate with the existing biology of the patient to give enhance healing and repair abilities. The units are typically implanted after puberty, and activated in maintenance mode until after menopause in women and at about the same time chronologically in men. At that time full anagathic activation takes place. Not every Highland citizen can afford or even wants implants.
Conventional medical nanotech is very effective against common injury and disease. Despite ethical considerations some individuals have been known to push limits and the technology is still new enough that some people have doubts about its possible side effects, both moral and physiological.
The Church's stand has been nuanced. Use by clerics is not prohibited, but the hierarchy has shown a preference for advancing men who have not taken the treatment to the episcopate. Many religious disdain the use of ANF as just another form of worldly riches, though they do not refuse more conventional medical nanotech treatments.
The treatment is recent enough that effectively almost all first generation recipients are still alive, so that in a medical sense the long term effects of the treatment are unknown. Not every possible disease can be conquered and not every trauma can be repaired, but many can. The fear of the Church is that physical immortality might overshadow spiritual immortality. That has not seemed to have happen yet, and since such treatments are considered heroic treatment it is not a sin in the eyes of the Church for a recipient of the treatment to turn off their ANF to allow their bodies to gracefully grow old.
With nanofactories the production of the ANF implants is neither difficult nor unduly expensive, however penetration into the Midlands is spotty at best. Penetration into the Wilds is almost non-existent at this point, though it is known a few Highlanders with the implants are in the Wilds.
