The heart of power

In case you can’t read the caption, the heart is a ridiculous machine:

“The heart is a powerful instrument, pumping about three thousand gallons of blood daily. In a lifetime of seventy years, a heart could pump roughly 77,000,000 gallons of blood — enough to fill a skyscraper — or raise a ten ton weight ten miles. In an hour, a heart could raise a man five floors in an elevator. Two hearts could provide enough power to drive a truck around the world in two years.”

Like I said, ridiculous.
