It was practically impossible for Sulu to imagine the world in 200 years - he figured it was going to be a lot like now, only with more technology - but he could still understand Ianto's point, at least somewhat. Ianto was interested in everything going on, and it wasn't so dull and peaceful that they were sitting around meditating or whatever - he'd seen scifi movies, after all. "Just don't tell everyone that you're pining for future food, right?" he said, laughing, "After all, I'm pretty sure they'd think you were crazy."
