Ric Flair to write a second Autobiography?

Now this piece of news does sound pretty strange for me. It seems that The Nature Boy Ric Flair wants to write a second autobiography. An inside source said that Mark Madden will work on the project and it does seem like all is true. Why would a wrestler write a second autobiography? Shouldn't an autobiography be just one? I am sorry but this is how I see it. I just think it is one way for a legend wrestler to gain more money. I might be mistaken but hey, I am entitled to my own opinion.
