Hiccups are incredibly irritating and they don’t seem to serve any purpose – right?
Scientists at University College London may have finally figured out why we get hiccups.

They discovered that when newborn babies get the hiccups, it triggers a huge wave of brain signals, and they teach the babies’ brains about how to regulate breathing. As we grow up, the hiccups stick with us, even though they don’t serve a purpose anymore. The researchers say they’re a, quote, “hangover from early periods of our life that persists into later life.”

That’s a rough hangover from the womb, don’t you think?
