Column: Human bodies are amazing

Every day, a heart sends 2,000 gallons of blood through our bodies, creating enough energy to drive a truck 20 miles. In a lifetime, that’s equivalent to going to the moon and back. Also in a day, the human heart beats 100,000 times, which is roughly 60 to 100 times a minute. That’s a boring, middle of the road rate since an Etruscan shrew’s heart beats 1,500 times per minute or 25 times per second.
