Pretty sure the white stuff is antiperspirant while the blue is just deodorant. Most scents have both kinds and the label should say which is which. I don’t sweat much myself so the antiperspirant def iritated me years ago when I bought the wrong kind.
Pretty sure the whole reasoning behind the eagles not taking the ring to Mt doom was because of the nazgul. That’s why Gandalf had the whole Hobbits sneak into Mordor plan.
