When I was a kid, I wanted to be serious, like Daniel Day-Lewis. No one really dreams of being a comic actor, do they? Now I realise how stupid that is - and it's because comic acting isn't taken seriously enough. It's a discipline. You know instantly - either you're funny and getting the laughs, or you're not.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.

The importance of heart health became very real for me when my father died of heart disease seven years ago. Having experienced the loss first hand, I am inspired to do everything I can to break the cycle and prevent families from losing loved ones to this preventable disease.
