Redditors have been sharing their favorite "myths that people still believe", and we're willing to bet you either believe one of them or know someone who does.
Here are a few of the best ones. As always, we'll jump in if anything needs elaborating.
Yes, there's a strange urban myth that if you swallow chewing gum it stays in your body for seven years to digest, with variations of it stating that it remains specifically in your stomach.

Yep. In fact, sometimes it hits the same person multiple times.
