For what its worth I can relate to that. Recently my wife said "I'm going to go out and buy us some cake". Two hours later she returned, happily bearing cake, and said "Yeah I got distracted hacking portals". She'd walked something like six miles. She's certainly keen, and enjoys it, though I've never really seen the point of it myself.
