I see Pilsu's point about medicine possibly being too complex an issue to "wave any wands" at it, but when I've had the chance to study Chinese medicine (and Indian, and Egyptian) in more depth, I plan on addressing this, since those fields of study involve themselves with holistic well-being, as well as the soul, as a part of the overall physical structure.
Since this is a fantasy environment, and since souls are going in, it's definitely something that we can't turn our backs on. Since it's DF, it's also nothing that can safely be only lightly touched upon.
It's really quite ironic that, in order to address the issues presented in a simulated environment, created for entertainment purposes, we're actually going to have to aim for something even *more* complex than actual, real life, Western medicine.
By the way, is anyone here very interested in actually persuing the study of ancient medicine, and the ramifications of medicine in a fantasy world? I'd like to form a sort of "academic circle", so that this can be gone into, in a lot of depth, and (hopefully) from a lot of different, educated perspectives.
If you have the time to commit (atleast a couple of hours a week), if you don't mind taking direction from me, and if you have a strong interest, please PM me, and I'll set you some goals.
I can promise that, if you're committed to learning, you'll learn something, and that might just add to your enjoyment of the game.
