Wedding ring is always on... intentionally bought one with with a low gold content - I think it's 9k white gold - so that I could wear it all the time and it would be strong enough not to get dented and mashed up all the time. If I had a 22k one like the wife, i'd have to keep taking it off as being clumsy man I would eventually damage it in some way.
She being a lady of course is blessed with the lightness of touch that enables her to wear delicate items.
