Your heart is the strongest and toughest muscle in your body. In 12 hours, the innate intelligence of your body can generate through your heart enough energy to lift 3 fully loaded Greyhound Scenicruiser buses one inch off the ground.
Your heart beats usually at about 75 beats per minute… or about 40,000,000 beats per year. These are only the beats you can feel (your pulse). Actually there are twice that many because your heart is a pump. It pumps blood from your body into your lungs to get renewed oxygen, then pumps it back into your body to supply new food to your tissues. Since both actions happen at the same time you can feel only one beat.
Your heart pumps about 2 1/2 gallons of blood per minute. If you could loan your heart to pump donor blood into pint bottles, it would fill so many bottles in one year that they would stretch from Washington D.C. to Orlando, Florida.
Amazing isn’t it?
