Anecdotally, I’ve noticed that I very consistently (as in, nearly 100% of the time) get hiccups while shaving, almost always whenever I get to the parts under my chin or the sides of my neck, with the severity getting worse the longer it takes me to do those areas. I’m kinda curious why that might happen, especially if hiccups have to do with food (I obviously don’t eat anything while shaving). Every time I’ve asked someone about this when the topic of hiccups comes up somewhere, they’ve told me this doesn’t happen to them and have never heard of it being a thing, so maybe I’m just weird that way? Kinda frustrating tbh as I’ve yet to find a way to prevent it.
