I see someone who has been woken up too early by their children: I have bags under my eyes. We have three children, and the youngest is eight months. We've had quite a few 5.30am starts - if it's not one of them, it's another.

I retired at the end of September, and one of the things I've enjoyed most is that I don't have to worry about training. At the beginning of January I thought, "I've got to start doing some exercise." On the first day, I ran for 20 minutes on the treadmill, did 20 minutes of free weights and did some core stability work. I did the same again the next day. On the third day, I woke up and felt so stiff, I said, "I'm not doing that any more", and that's all I've done in eight months. I'm lucky my metabolism and body weight haven't changed and I still look the same.

I am the ripe old age of 33. Ageing doesn't bother me in the slightest. I'm lucky to have a pretty thick head of hair, which is going to be cut today - it's a mess. I don't have any grey hairs. I expect they'll come soon, but I won't be reaching for the hair dye. People ask about plastic surgery, but I have no desire to change anything. Lines are part of your character. I don't use moisturiser or go in for grooming beyond brushing my teeth.

The whole appearance thing is a bit superficial. If someone thinks that I'm really ugly or that I'm attractive, I think, "Whatever." What's on the inside is more important to me. I have two older brothers, but we don't look alike. Am I the best-looking? You'll have to ask my mum.
