Sure, you know how to steal hearts, win hearts, and break hearts. But how much do you really know about your heart and how it works? Read on to your heart’s content!

• Put your hand on your heart. Did you place your hand on the left side of your chest? Many people do, but the heart is actually located almost in the center of the chest, between the lungs. It’s tipped slightly so that a part of it sticks out and taps against the left side of the chest, which is what makes it seem as though it is located there.
• Hold out your hand and make a fist. If you’re a kid, your heart is about the same size as your fist, and if you’re an adult, it’s about the same size as two fists.
• Your heart beats about 100,000 times in one day and about 35 million times in a year. During an average lifetime, the human heart will beat more than 2.5 billion times.
