What's your attitude to health?

I've probably got leftovers from the army when it comes to my health. I understand you have to look after yourself to keep the machine working. Having said that, I'm also quite happy to abuse myself.

How much sleep do you need?

Sometimes I turn up to early morning radio shows without having slept at all, which is fine. Our shows finish at midnight and you have to party afterwards.

Do you worry about your weight?

No, I'm not too fussed about it. When I'm on stage I'm running around for an hour and a half, so I get a lot of exercise. I also live it up; my home is in Ibiza and I go clubbing a lot, which means jogging on the spot for eight hours.

Is sex important to you?

It's as important to me as it is to the next man, and, you know, it's pretty important to him.

Is there anything you swear by?

I don't agree with superstitious routines, but there are a couple of things I'll always do before performing. I'll get together with the band and chill out, and then, just before I go on stage, I'll always check my flies.

How much do you drink?

I don't drink before shows, because I'm singing songs about what it is to be conscious and it would be really bad to be unconscious. But after the shows, yes, we like to drink. At four in the morning I'll have anything that's going. After every show we have a party. Eighty five concerts every year means 85 after parties in 85 different countries.

How do you relax?

I relax by catching up with my friends and family. When I am at home in Ibiza, I find the contrast of living on a divided island relaxing - with beauty and tranquillity in the north and a sense of fun, shallowness and celebration in the south.

What's your attitude to smoking and taking drugs?

I think you should be educated and informed about the pros and cons, and make your own choices.

Have you ever had therapy?

Every time I do an interview, it's like serious therapy. But real therapy isn't something that I'd ever have. I feel fortunate that mentally everything is functioning well.

Are you happy?

Sometimes, reading my own media, the negativity can upset me, but I just deal with things on a positive basis. I mean, I have up to 20,000 people singing my words back to me on a nightly basis - they share my hopes and fears, and they relate to my own life experiences. Life can be pretty isolating, but that connection is always amazing. I am happy. Yes, very.
