My recent battle with cancer.

I’ve been to two postmortems in real life, and spent the last 14 years talking about death at work – so, pretty close.

It is a very rare affliction. A GP would expect to meet it once in a career and this form of brain cancer is unpredictable and dangerous. Usually, this tumour might give you only a two-year span since its discovery. I have had two operations and one course of radiotherapy and now three chemotherapies (one currently starting). My death is, in a sense, imminent. I say to myself: I am dying. Something in my head is hurrying to kill me.

I had heart surgery when I was 17. The other time was when I fell off my piano. My head was an inch away from a metal step.

When I had my first kid and when I had my first big success with I Gotta Feeling.

There are types: there is the world-being-comfortable type of love and there’s the lust-and-passion type of love – I think I like that one better.

People worship music artists or actors but I have a lot of admiration for doctors, people who save lives.

Giving DJ culture more respect.

I guess I would wake up, have breakfast with my children. Then I’d go to the studio and make the best record of my life, and then have a lot of sex! That sounds pretty balanced, I think!
