We’ve mentioned before that a great way to know if you’ve been washing your hands for 20 seconds is to sing the “Happy Birthday” song while you wash.

Now I’ve got another germ prevention tip.

If you’re a big fan of The Smiths (and, really, who isn’t?!), you can ALSO sing the chorus of “UNhappy Birthday” which is just about 20 seconds as well!

This, folks, might be the most awesome scientific breakthrough since the whole BeeGee’s “Stayin’ Alive” CPR thing.* Pass it on.

* Note that, in this case, the opposite works as well. Queen’s “Another One Bites The Dust” provides an equally useful CPR beat!
