For countless times in my childhood, I was told that if I ran or jumped after eating, rice (or other food, but let's face it... I mostly ate rice in those days) would fall into my appendix and lead to appendicitis.
The rationale is that rice or other small food particles, while passing through the large intestine (to which the appendix is connected), can get jerked into the opening of the appendix. When the appendix cannot flush itself out, it gets infected, and hence, appendicitis.
NOTE: In biology and physiology (waaay back in high school), we learned that the appendix is a vestigal (aka, useless) organ that lost its practical use over time. It used to create enzymes to help digest the "rough stuff" like weird plants that humans/humanoids used to eat. Over time, as we cooked our food and narrowed our diets, the appendix was no longer needed. Instead, it dangles on the right side of the large intestine.
As the good (yeah, right!) kid that I was, I abided. I guess moreso out of fear. And to this day, although I took biology, physiology, and even Googling-ology, I still have this tiny superstition that this could be true.
Having somewhat of a family history of this scares me. One of my parents was struck by this more than 10 years ago, supposedly due to rushing to places after meals.
Using Google has not really helped allay my suspicions. This site claims it can't happen. And based on the explanation I gave above, it shouldn't... right? I mean, by the time we're talking about large intestine, "rice" is no longer rice... by then, everything is poop (how many applications could THAT phrase have?). So if anything were to "fall" into your appendix, it wouldn't be something that could merely just happen after eating... it can really happen ANY time your digestive system is not empty (which, short of colonoscopic cleansings, is atypical).
Of course, I don't run after eating, because running or anything on a full stomach feels terrible in other ways. ;)
Has anyone else been told about the appendix "myth"? What are your thoughts on this?
