Generally speaking, wearing rings is based on three things. They are Tradition/Affiliation, Style and Comfort.
The reality is that rings send a message. For thousands of years, men have worn them to signal status, wealth, commitment, and association. They can send the message that you’re not available, that you attended the Naval Academy (yes, I see your ring Annapolis man), that you’re part of a fraternal brotherhood, or that you’re from a culture not afraid to display wealth on the hands.
