Why does the left hand mean marriage?

Question:This is more about why we wear a wedding ring on our left ring finger, this is what I found:

It was once believed that a vein of blood ran directly from the third finger on the left hand to the heart. The vein was
called vena amoris, or the vein of love, and early writings on matrimonial procedure suggested that it would be
appropriated for one's wedding ring to be worn on that special finger.

because the ring finger has a blood vessel that runs straight to the heart, thus meaning you give your heart to the one you married. as to the rest of the fingers have blood vessels that connect to other vessels before the blood flows to the heart.

The left arm is closer to your heart than your right arm.

Its tradition - People used to think that the ring finger on the left hand had the quickest way to the heart.

left at first hopefully not later when you wished you had been right instead of left
