I had a financial page to write in the Mail on Sunday where I'd give tips on shares. I worked there for two and a half years. Nothing compares to the burst of energy felt on a newsroom floor when a big story breaks.

I'd like to be a geneticist to be honest, but there are limits to what I can do now. For my dream to come true I'd have to be 20 years old again, heading off to a blue chip university.

I'm working harder now than ever before. I couldn't turn down the BBC job because I've never been offered the opportunity of killing three or four people on screen before!
