Is it true that your ring finger on the left hand goes directly to your heart?
Sadly, no. The vena amoris (lit. 'vein of love') does not exist.
It was a romantic myth created back starting from early civilization where the heart was considered to be the center from which all emotions sprang. As thus, the ring finger upon which the wedding ring being placed being that mystical link to the heart was a fanciful and beautiful one.
However, scientific evidence and proof has shown it does not exist.
