That really sums up the strange bluntness that a really prime German interview can have. They're really interested in your cultural velocity in this way that I don't think people in the United States even necessarily think about alternative-rock bands. So it's not like we're against regular rock. We're not like a battling army shaking our weapons against The Rolling Stones.

A lot of times I'll post things on Facebook, and the immediate response will be like, "Stick to the music!"

Sometimes you have to wonder if there isn't an ejector seat built into having a popular-music career. We were lucky when we started. We were already old when we started - you could have described our first album as "aging Brooklyn guys." We were in our late 20s. We weren't octogenarians, but a lot of bands were already younger than us. Fortunately, we've held on to our manly good looks.

If you do believe in science, you really have to actually stand up and make a stand for it. You can't just say, the facts aren't in. Science is always looking for better explanations to everything, but that doesn't mean that when we get on a plane we don't know what's supposed to happen next. And if it doesn't go the way that it's planned, that's a big, big problem. The culture wars are very tricky and make me a little sad.

If you're looking at the array of performers, there's just a lot of people that it's about getting closer to them. That's not really our focus. It's funny, with the kids' stuff, we really sell ourselves as the MC, but it's much more like we're Ed Sullivan than we're like Sting. We're just the presenters. And that's an idea that we're very comfortable with.

I feel like the future is unwritten. So many of the things that we write now haven't been about educating people on the environment, they've been about disseminating facts. But I feel like it could be productive to write something that explored directly the idea of fragility.

You're like, "I don't want to argue with Dr. Drew on national radio." You're like the invited guest. But at the same time, as a thinking person, it's very difficult just to stand by and go, "Yeah, man, it's cool."
