Utterly Mad

I mean, I would. Dirty clothes would get into your wounds and you need vitamins and minerals to survive mengo.

Plus technically overall dirtiness has a thing in DF, and it factors into infection from injuries.

Thing is, I don't know if CDDA filthiness affects the healthiness stat or odds of infection from injury. I recall when I first saw the filthiness idea, likely in the bad ideas thread. I suggested it WOULD be a decent idea if it had DF-style effects, and was more than just a morale effect like 90% of the dumb shit (shaving, haircutting) that was making it in at the time.
