Happy Valentine's Day!

Have you ever wondered why the shape that is known as a heart, called a heart when it does not look like an anatomical heart?

There seems to be quiet a few explanations and controversies surrounding this..

• During the seventh century B.C., the city-state of Cyrene had a lucrative trade in a rare plant: silphium. It was reputed to be a form of birth control. The plant's seedpod looks like the heart shape we know today. The theory goes that the heart shape first became associated with sexuality, and eventually, with love.
• Some say that in the 17^th century, when a saint had a vision of the 'Heart' surrounded by thorns, it became known as the Sacred Heart of Jesus and was associated with love and devotion
• It is said that the shape of heart matches that of cattle more than human and as ancient beings had only known the insides of animals, that shape probably got associated for a heart.
• It's also said that the drawing of a modern heart possibly originated because of drawings of the human heart by medieval artists after a philosopher inaccurately described the shape.

Well, what ever may be the reasons, the shape turns out to be just fine because if we had to replicate the human heart every time, every one around the world would have to spend a lot more time in their biology classes.
