I never take my wedding ring off, it just doesn't feel right.
Once a year or so, I apply some metal polish (Autosol - made in Germany,
www.autosol.com) which rubs out minor scratches which renews the feeling.
Yes, wearing a ring, watch or similar foreign object increases the risk of injury. But imagine the impression on your wife, or husband, if you can report rather losing a finger than violating this symbol of your special bond.
On the other side of the argument, my own father had to take off his wedding ring when he went into the hospital, somewhere in the fifties, and as a result it went missing and, for as long as I knew him, he wore no wedding ring. My parents did stay happily married for 53 years, so wearing a ring is not actually a 'must-have' prerequisite to a long-lasting marriage.
