I forget how old I was, but at some point as a kid I had this really big marble, and as dumb kids sometimes do, I kept sticking it in my mouth for no reason. Eventually I accidentally half-swallowed it and it was big enough to completely block my throat. I couldn’t breathe or make a sound, and I don’t think anyone else was even home at the time anyway. I legit thought I was gonna die, as much as I could process that as a kid, but I somehow managed to cough the marble up after a few seconds. I distinctly remember thinking to myself “okay don’t do that again,” and then absently sticking the marble back in mouth a minute later anyway.
