Question

Why do people have a common belief that the heart is located on the left side of the chest?

Answer 1

People have a common belief that the heart is located on the left side of the chest because the narrow end of the roughly triangular heart is pointed to the left side and during its working, the contraction of the heart is more powerful on the left side which can be felt. Actually, it is right in the centre between the two lungs and above the diaphragm.
