Richard Dawson has been delivering mail in Lansing for 56 years and has been on the same route for the last 30 years, the Lansing (Mich.) State Journal reported Sunday.
Although he admits that he has considered retiring before, he said he doesn't plan on doing so any time soon.
"I have to have something to do," Dawson said. "There's times I would like to quit. But, when I have a week off and don't have anything else planned, it gets boring."
Dawson said he even has about two years of unused sick time built up.
"He would much rather be here than anywhere," his delivery supervisor Guy Kaltner said. "It means the world to him -- getting people their mail."
