ボクはのどにつまる時「あーこれなんかのどに違和感ある、多分つまりそう、でもクチの中にあるもの飲み込んだろ！」っていってつまります。亀の甲より年の劫、経験がものをいいますね！

Whenever I'm choking, "Ah, somehow my throat feels uncomfortable, that's more or less it, but I can just drink to swallow the things in my mouth!" is what I would say. Sense comes with age, and experience speaks for itself!
