Sophie Ellis-Bextor

Philately is normally a boys' hobby but for some reason it was in vogue at my junior school. Between the ages of eight and ten I collected avidly. I'd pore over my Stanley Gibbons book, obsessively checking my collection's value. I always hoped I'd stumble across a really valuable one, a Penny Black or an Inverted Jenny, but it wasn't to be.

Do I sometimes hope I wake up in the morning and people are like, 'What's wrong with her? She looks emaciated.' Of course I would love that. I'm such a clothes whore, I would love the opportunity to be a hanger. But I think I'm more confident than I've ever felt in my life.

I want to tell mayors, county chiefs and heads of big companies: don't just chase GDP growth; don't chase the biggest profits at the expense of our children and grandchildren and at the cost of sacrificing our ecological environment.
