Loneliness (and the lack thereof) comes from within. I have wonderful friends and family all over the world that I keep in touch with in various ways, and there are wonderful people surrounding me wherever I go. Plus, I'm not constantly on the road. Last year for example I stayed at home with my wife all year. And honestly, you can feel pretty lonely being pressed together into a metro-train with hundreds of other commuters. So no, I don't feel more lonely than when I'm "at home".

Lol, exactly what I was going to reply about New York City for example... I think it's one of those places where ypu can find some of the loneliest people on earth! Wild stuff.
