User blog:Randomname12342/Roger as a rookie in Brook's days?

I just finished the Thriller Bark Arc and I remember someone said something about Gol D. Roger and Brook replied something like "Gold Roger? I think I remember a rookie by that name from a while ago." Well, the thing is... Roger is 53 years old and Brook was a pirate 50 years ago so does that make Roger a pirate when he was 3?
