Introducing a new colour of the classic, 'To The Moon & Back' series. My dad used to say this to me when i was a little girl, and it never gets old.

So how much are we talking? In one year, the human heart generates enough energy to drive a truck 7,300 miles (20 miles per day). If we consider the lifetime of a human to be 70 years (UK average is 82 but other countries much lower), then our heart generates energy enough to drive a truck 511,000 miles.

Consider this: 20 miles x (365 days/1 year) x 70 years = 511,000 miles. The distance of the Earth from the moon is 384,400 km, which is approximately 238,855 miles. To the moon and back to earth, 238,855 miles x 2 = 477,710 miles. Therefore, when you say you love a person to the moon and back, you love this person with all the blood your heart has pumped... your entire life. And some more.
