In Japan, Mochi is sometimes enjoyed during parties and festivals.
It is very chewy and tough, and sometimes it can be hard to chew up and swallow. This is dangerous for old people.
Sometimes, in Japan, old people choke and die by eating Mochi.
So, there are public safety commercials for old people, to please be careful eating Mochi during festival season. Take small bites, only eat it when there's other people around, etc. And if you choke, someone can use the Heimlich Manuever.
