Fear of others choking!

It's not a fear of choking! I'm quite confident in my own ability to consume and swallow food. However when I eat around others, I begin to worry that they might start choking, and I will need to perform the heimlich maneuver on them. This is especially worrisome around toddlers and infants! It's most scary around large people who it would be difficult to perform the heimlich maneuver on. This has caused me to avoid eating meals with people, as well as have to excuse myself from many meals with others.
