I've heard/read different things as to why Marciano retired, along with back problems, I read that Rocky had taken a lot of trauma to his head. I also read somewhere that Marciano decided that he wasn't going to give his Manager Al Weill another big chunk of his purses. To be honest I don't know the real reason.

A bit of trivia: A few years after Rocky retired in Sept. 1955, then Heavyweight Champion Floyd Patterson, was KO'd by Ingemar Johansson. Marciano considered a comeback, but after only a month of training in three years, he decided against it and never seriously considered a comeback again, that was in 1959.

BTW, Marciano was only around 32 when he retired, and on the eve of his 46th birthday when he died in August 1969. He was still a young dude.
