Wedding rings are worn on the left hand's ring finger because it has a vein inside it that is supposedly connected to the heart..
I know it's not an actual fact about the heart but I thought it would be quite interesting, sorry if this doesn't actually help =p

It takes 20 seconds for your blood to go through the entire vascular system
The humans vascular system is 96000 kilometers long
And that means that your blood is going at exactly 17280000 kilometers a hour or 4800000 meters a second
I only know this because I'm doing a project on pulse and wanted to find fun facts
