They're still advertising the added health-giving advantages of vitamins in your daily diet, although it has long since been shown that you'd be better off eating Smarties.

I don't do a lot when I'm in Gascony. I swim and play the odd game of golf, but mainly I sit around. We're set an hour-and-a-half from the Pyrenees and an hour-and-a-half from the Bay of Biscay, so we get plenty of storms. But we're surrounded by vines and sunflowers - it's lovely.

The BBC knew I was successful from early on, but they weren't sure why, and they still aren't sure. What I do has been unconventional from the beginning, so they've never been sure. It just works. It just does.

Nobody ever texts me, because they know what I'm like. I'm a constant frustration to my children because I never switch my mobile phone on. I only use it when I need to make a call or when I'm stuck somewhere or lost, then I switch it off again. I've never texted anyone in my life, and I'm not sure I even know how to.

I have to say, without getting up on a soapbox, I find these reality shows absolutely disgusting.
