We even learned how to conduct a self-Heimlich using a plain deskchair in the event you found yourself choking without assistance nearby. I'd imagine it would be difficult to maintain composure when you feel your air being restricted.
That happened to me one time. "Maintaining composure" was really hard when I was choking to death. I knew I was dying. I prayed. It came into my head to use my desk chair. The food I was choking on FLEW out.
My words here do not even come close to describing the incident. But I guarantee I have been more careful since then.
Choking to death is a horrible and painful way to die. I hope that teacher suffers severe punishment.
That's what I get for posting before I've read most of the comments. Please scratch my last sentence
