That's bull. It's a westerners point of view. All of fingers are very important, so why should we wear a ring for just our wife/husband? It's capitalist point of view so that you can buy more products. Now a day, you have father's day, mother's day, valentine's day, earth day, christmas day, women's day, happy birthday, garden day, girls nightout, etc.
well bro Tinko, most people are right-handed so they usually wear the ring on the left hand avoiding to damage it when working. By the way, my wife got angry every time she saw me without it saying "you're like a dog without collar" (she means a bachelor) Hahaha ! Go to understand women , my good fellow !
yea, ok... this sounds like a bunch of hippie nonsense...
anyways, the wedding ring is worn on that finger because people of long ago believed that the vein in the left ring finger was directly connected to the heart. its that simple.
