Fair points. I'm a fan of good sanitation myself.For me it all comes down to two aspects:
1. Storytelling / Worldbuilding rigour;
1. I absolutely, utterly, unwaveringly detest and loathe lazy handwavium alla Deo ex Machina. With this in mind it is simply a question of statistical levels of rigour. From all the fantasy and scifi I have read the balance comes out slightly in the favour of scifi.
2. Almost all retero-historic works run into the question of plumbing and soft toilet paper. It is a question of pragmatism. I simply don't like the idea of not being able to wipe my behind without it itching insufferably.
With this in mind, if I must vote for only one despite having a fondness for both, it must be the logic cistern of science fiction.
Oh contrare! I know of at least one SF book ('The Ice Palace' I think it was called) that addressed sanitation and hygiene quite well.As far as I can tell, in neither Sf nor fantasy does this question ever arise
Indeed. It is true, though, that cleaning magics in a lot of magic-containing fantasy milieux are rather basic and commonly used. Unfortunately, the D&D group of which I'm a part seems to have ground to a halt - but I came up with the idea of a gambeson (look it up!) with permanent magical enchantment to keep it clean and dry. Using their rules, it would be rather cheap - and probably rather popular with warrior-types especially those who commonly wear heavy armour. Much the same enchantment could be applied to the armour itself; armour that never goes rusty would be even more popular!There are many possible sources of fetid stenches, and while they often involve poor sanitation, the issue here seems to have been soft toilet paper -- and that has little if anything to do with sewers and stenches...
Underdeveloped drainage, as you put it, existed long before there was soft toilet paper.
And who ever said that all the butts in fantasy were clean?
My point was primarily aimed at the fact that very seldom do either fantasy stories or sf stories actually get into such issues -- a fact of which I'm glad.
