We used to learn some basics in middle school...and about a decade later I was able to save someone 'on the spot' who'd eaten too much (at once of anything really) stringy roast beef...
.It helps to review every few years and really 'the more often the better..." especially for youth, elders or others who may have trouble chewing (and may have food get trapped or pocketed between the teeth and cheeks) and be aware some people cannot drink water but need a thickened liquid or juice.
Preventing a lot of basic problems is a lot easier than having to address concerns people aren't aware of.
