Ever saw animes where characters pound mochi and you wanted to eat that ? But did you know that mochi / rice cakes can kill ? Making you choke on them and you suffocate if you didn't chew a lot ? There are always some kills in japan because of that. Despite never ever tasting mochi in my life it scared the shit out of me because i thought i could have happened to me who don't chew a lot. In short, the part in Daily lives of highschool boys where they choke on mochi really can happen.
