Just because you've heard it before, doesn't mean it's true.
A recent Reddit thread asked the internet to share what widely accepted "common sense" is actually wrong, and a lot of the phrases we've been hearing since childhood have been made up by the No Food in the Pool lobby.
While Reddit might seem like a weird place to have myths debunked, I fact-checked these to make sure it's not even more fake news.
Do not, EVER, wait 24 hours before filing a missing persons report. If you have a reasonable suspicion that something happened to someone, call immediately!
