Perhaps this fits into the “lots of things will work if you’re motivated” category. When I was a kid, that was my theory about hiccup cures. There were so many different hiccup cures (holding your breath, drinking a glass of water slowly, getting startled, . . .) and they all seemed to work, so I decided that just about anything would work to cure the hiccups, if you wanted it to work and you had a plausible enough theory attached to it.
This is not to disparage Matt’s plan. It seems to be working for him, which is what’s important!
