So Sauron '
stank', did he?
Not surprising, but was this only when he was '
unclad' (as in having no physical form, not as in having no clothes on), or when he was in physical form?
If the second was the case, then he would have had to be careful, in the days when he wore a fair form, to keep himself very clean to avoid detection. Perhaps Middle-earth owed a lot to his taking regular baths and developing the deoderant. Did orcs and others who acknowledged his rule fear him because he insisted that
they also wash regularly?
Of course, this would have to have been before the Downfall of Númenor. Now that he was stuck in the form of a dark lord, he wouldn't need to bother with such cleanliness. Perhaps he then abandoned it, and his people followed his example...
