Another one I'm not sure how to fully explain: closing the nose without touching it. I can fully block smells or breathing by doing something that feels like inflating a zone between the top of the mouth and the nose. When speaking it will sound as if I am pinching my nose without hands. Comes in handy when having to face horrible smells. I assume everybody can do it but many don't know how. https://www.reddit.com/r/TooAfraidToAsk/comments/ysd5o2/is_it_uncommon_to_be_able_to_turn_off_your_nose https://www.reddit.com/r/TooAfraidToAsk/comments/ysd5o2/is_i...
