When I get tired, I start eating things that I wouldn't normally crave, like biscuits, because they'll give me a bit of energy to keep going.
I can't be bothered to go to the gym, though. I honestly just can't be bothered - it's the most boring thing on Earth. I have tried and every six months I go 'right, I'm going to the gym'. Then I do it for two weeks and get so bored by it.
I loved doing 'Countdown.' I now consider that I was very, very lucky - not just because it was such a wonderful show to do, but because it lasted for so long.
Since I turned 50, I've had the best year of my life and I now throw as much effort into the social side of my life as I do work - more so now than ever before.
