Yawns? Hiccups? Goosebumps? Shivers? They all happen for a reason. Kimberly Fusaro of Woman's Day spoke with Eric Plasker, author of The 100 Year Lifestyle to find out why our bodies do peculiar things. Take, for example, hiccups:
If you’ve frequently got a case of the hiccups, try slowing down when you eat and drink, suggests Dr. Plasker. Doing either too quickly causes your stomach to swell; this irritates your diaphragm, which contracts and causes hiccups. You may also get hiccups in emotional situations or if your body experiences a sudden temperature change. In both of these cases, the hiccups are a result of a glitch in your nerve pathways, which is why a sudden scare—which might shake up and reset your nerves—can sometimes end an episode.

One of the commenters is quite bright: They claim that the explanation for why we yawn can't be right because fetuses yawn and they don't need oxygen. No. Of course fetuses don't need oxygen. None at all.
