ehmm, yes, I guess it could be interesting, but, did middle-age europe have chiropractors? I thought chiropractic was only something fairly modern? Anyway, healing them from fatigue could be done buy mixes of herbs, or a special potion, or even buy giving gifts to Talad or Laanx.
lol, in Middle-Age, they kept wounds open until no more blood was left within the person, because they thought that the blood was the evil within a person ...
