You could save someone's life by knowing 'Teardrops On My Guitar' by Taylor Swift -- seriously.
According to the American Heart Association's new CPR education campaign "Be the Beat," one of the key components of the life-saving resuscitation method involves chest compressions, which should be performed at 100 beats per minute.
How do you figure out what that rate is?
Just remember one of many tracks you already have on your iPod, such as Taylor's sweet love song, Michael Jackson's 'Man in the Mirror' or Justin Timberlake's 'Rock Your Body.'
