I can do that!
To a degree at least, just got gratually better over the last few years without deliberate stretching or severing anything. Altho I mostly use it to get slime out of my throat instead of caughing. Now just tried it to get up to my nose, nothing there at the moment.
I guess I am almost at the "third stage" distance wise.
It helps to exhale quickly to get the meatflap out ontop of the thongue. (Second picture)
I've did research if one could choke on their own thongue several times, because I was worried that it would "fall down there" or get stuck or sth, like a dislocated jaw or a scrotum torsion or sth.
Imo its the other way around. If you experience art, you think about it and try to get a meaning out of it (even if there is none, as in some modern art pieces). But if you just play a game you are not getting the art-aspect of it, you just enjoy it for the gameplay or maybe even the story but not for the deeper meaning.
