I tried to draw people more realistically, but the figure I neglected to update was myself.

It's a visual world and people respond to visuals.

Oh, it's essential. I mean, you have to - if I'm writing about the Middle East, I have to go there, and if possible, stay long enough to get a real feeling for what's going on.

I'd rather go to a place and spend a couple of months, get to know it, get to know the people.

And, in some ways I like traveling, in other ways I'm sort of fed up by the whole notion.

With comics you can put interesting and solid information in a format that's pretty palatable.
