Why Is the Heart Associated with Love?
From the earliest experiments in anatomy in Egypt in the second century BC, the heart has been associated with emotions.
As scientists followed nerves around the body, they saw that the vast majority of them seemed to lead to the solar plexus in the chest.
This gave rise to the theory that the heart was the seat of emotion and reason. It was considered the basis of thought.
Later, the Greeks believed that the heart was the seat of everything; similar to our belief that the brain makes us who we are.
The idea is reinforced by the fact that our heart pounds when we get excited.
