Gavin Friday: Alcohol. If I open that bottle, I can stay up and then I love that if you go out and you have a great meal with friends and then you go home with a few friends and you have a late night disco. I mean, you're not dancing on the table, but you open another few bottles of wine, you've great friends, and you're playing music and talking rubbish. That's a great thing on a weekend. So that keeps me up late. I tend to -- in the last couple of years, because I used to live right in the city center, I've moved out to the sort of not the city center: county Dublin, near the coast. So I tend to get up early now. I'm known to get up at 7:00 in the morning. I like swimming because I have a bad back. I have no choice there. I write and I sometimes go to bed at 11:00 and then sometimes I go to bed at 5:00 in the morning. That's when I go out. But worry, I get anxious but worry doesn't really do any good. If something is broken or in trouble, you've got to bend down, pick it up and fix it. Worry just makes us get wrinkles. So try not worrying.
