Right now, while you’re reading this, your heart is working hard. It never stops — not even when you sleep!
The Numbers

How Hard Does It Work?
Your heart pumps about 7,500 liters of blood every day — enough to fill 50 bathtubs! In your lifetime, your heart will pump about 250 million liters — enough to fill a small lake!
Heart Sizes
Your heart is about the size of your fist. Try clenching your fist — that’s approximately your heart’s size.
