Just for perspective: I am a man in my mid-40s and for as long as i can remember i had this question… is it normal that i can shut my nose close just with some muscles?
I always wondered why some people hold their nose shut with their fingers while jumping into a pool or when exposed to some horrible smell… i never had this need. Changing my sons diapers? No problem! Cleaning the latrines while in the army? Just a breeze!
Ehm… yeah… just thought about this…
Basically what happens when you look at your nose. But it’s also possible to e.g. only move one inwards while keeping the other straight. It’s not difficult, but there are people who can’t do it.
Oh ok, I thought you meant pulling the eyeballs “inwards” as in towards the back of your head! What you describe, I’d normally call “crossing” my eyes.
