I am not at all a politician. I don't think I'm cut out for politics. I am certainly not going to stand for election.

I met my wife Anne who was a sociology student, and her influence together with activities associated with the student movement of the time opened up my interests amongst other things into the theatre, art, music, politics and philosophy.

I'm not very active politically. The causes I work on offer immediate, practical, accessible help, and politics has never meant that to me.

Is anyone serious about the politics of happiness? David Cameron dipped a toe in the water, using the word lightly, but denying the hard policies it implies. Labour shies away from it, but should take up the challenge.

My job is to look at what politics is doing, not be a politician myself.
