My wife's biggest fear is air pollution, living in London as we do. She's convinced that's the big problem. And my own is sink holes and the inevitability of us all, at some point, collapsing into a sink hole and never being seen again.
OCD is a really serious condition - it's a proper thing. It's not just, 'Oh, you like your pens to be straight'. For me, it would always go in tandem with being unhappy. The unhappier I was, the worse it got.

I certainly tried to talk about less complex things, but I've had to accept that it's just not what I do. That isn't to say that my shows are depressing - they aren't. At least, I hope they aren't! The problem I have with stories about happy things is that they don't require any skill from a comic - they just repeat the details verbatim.
