You can also retire other things, for example sports teams sometimes retire the numbers of famous players.
"Luke Appling played 20 seasons with the White Sox and is the club's all-time leader in games, at-bats, hits, doubles, runs and walks. He entered the Hall of Fame in 1964, and his number was retired in 1975." http://chicago.whitesox.mlb.com/cws/history/r...
Or you can retire horses from racing:
"He was retired from racing at the end of a very successful career. His kind owners would like him to get a new home as a pleasure horse." http://www.nyhr.org/horses.html
