31 and loving Minecraft. My wife doesn't get it either.
The server I frequent has a bunch of older players as well, and also some of their children. It's always amusing to check out the kids' part of the city, it's like some crazy ramshackle ghetto.
If you mean "use Nether portals to travel from map to map" that's one thing. If you mean "take multiple maps and combine them all into one giant map to use on the server" that's another.
