Who knew that something as simple as washing your hands could be so ... complex.
You just squirt on some soap, wave them under the tap and then dry them on your pants, right?
Well it turns out we've all been doing it WRONG. Just like you've been using Post-It notes and chopsticks wrong. You silly.
The New York Times published an article last week stating that scientists in Scotland have confirmed that the handwashing technique recommended by the World Health Organisation is the most effective when it comes to blasting bacteria (they pitted it against the Centre for Disease Control technique, and the WHO one came out on top).
It also takes a mind-boggling amount of time to complete. It'll take you 42.5 seconds to wash your hands properly, which basically means you won't have time to watch the new season of Game of Thrones this year.
