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.
I'm neurotic by nature, but I'm wary of becoming more of a play than a comic - you don't want people coming to see a man having a breakdown for two hours. I'd prefer them coming to hear my astute and witty observations.
To say I wasn't such a hit with the ladies would be a very kind way of putting it. I was a slow burner, shall we say.
When you're single, you're not beholden to anyone, and you can shut down more easily. In the past, I had the idea that I'd live in a caravan with a dog near a pub with no responsibilities. But now, when bad things happen in the world, I feel responsible for them because they're going to impact on my daughter.
Early thirties for women is a very intense time. If you want kids, and you're not in a relationship, there's an urgency there, so they're forced to mature quicker. It's easy for a man in his thirties to be immature - you can have kids into your fifties, whereas women just can't.
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.
The only big life challenge I think I'm worried about is a mid-life crisis because I've done so little. I think if people who've lived normal lives have mid-life crises and buy motorbikes, what is a man who's done nothing?
When I'm filming a documentary, I feel like I should be the straight man, watching with a raised eyebrow.
'One Leg Too Few' by Peter Cook is a perfect sketch. The setting is ridiculous, the language is beautiful, and the performances make the most of every syllable and movement.
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.
