I don’t mean to get involved in this argument, but I thought it would be interesting to mention the history of men wearing wedding rings. According to sources that I’ve seen, men wearing wedding rings is a pretty new-fangled thing.
I’ve heard that it was an idea that jewelers came up with in the late 19th century so as to double their sales (this should go in the “yiddishe kop” thread). The idea picked up momentum during the Depression and by the 1940s the vast majority of weddings involved giving a ring to the man. So a man close to 100 would have been around marriagable age back then. A man close to 150 would give you a different story.
