I can stop my hiccups after a single one. There's a bubble of air that causes them and I can trigger a burp that releases it. It's easy! But no one else ever seems able to do it.
I read an article recently about doctors desperately trying to figure out what causes hiccups to help sufferers who can't stop having them, and it made me think I should volunteer for studies. But no one believes me, that this is my magic power. I bear my mark of glory silently (except for this chost)
