I wonder the same thing too, I mean how old is tsunade when she took the job and how old is she now? Like 52 years old or something.
Hiruzen was 68 when oro killed him, minus 12/1r years and we're back to when naruto was born and the fourth died.
Now 68-12/13=56/55 so let's say Hiruzen was 55 when he retook the job, so how old was he when Minato took it from him, I'd say Minato was hokage for 3 years max before he died, and that puts Hiruzen at age 52, the same age as the current sannin. Which begs the question, if Hiruzen retired at the age of 52 because of old age, why the hell did the leaf choose tsunade/jiraiya at round about that same age, how long did they expect her or Jiraiya to stay in charge?
