In the "old days" when even great fighters were not making millions of dollars, money was the main reason why washed-up fighters kept going. Sugar Ray Robinson, Joe Louis and Ezzard Charles come to mind. Nowadays it's more often due to an addiction to the fight game (Hearns, Leonard, Holmes) and\or the stubborn belief that you can recapture former glory (Holyfield).
A few fighters retired at just about the right time. Lennox Lewis, Henry Maske, Darius Michalczewski and Marvin Hagler are good examples.
