Name 5 ACTIVE boxers who have fought in 4 decades?

[Maravilla2012]

I can only name 2 maybe 3. Hopkins and Jones Jr. comes to mind. Has Holyfield announce his retirement yet or still fighting?

going on theme of those fellows, how about james toney, he must be close ? I am just guessing though

I was also gonna say Tony but he started in 1990
