What's the Gap Between the First Mission and the Second Mission?

He starts out as a missionary. And one of the things that amazed me was, this is a person who never really came home from his mission. What's the gap between when he comes home from his first mission and when he's sent back? Oha, about three and a half years m he's only 27. His wife is 24 when he's called to be the mission president. This is as mission president. It must have obviously been a little bit different in the way it functioned back then,. tham, the way it functions right now.
