I have no interest in Twitter or Twotter or Twatter. It would never occur to me to use it. People who Tweet during programmes are always asking, 'What happened then?' If you're bloody Twittering away all the time, you miss what is actually going on.

While I'm hale and hearty, I've no thought in my mind to retire.

I was 25 when I'd told my parents that I was giving up steady work as an electrician to become an actor. They couldn't have been less enthusiastic if I'd proposed starting a commercial newt-breeding operation in the bathroom.

I never thought I was academically gifted at school. But when I started flying, I found you didn't need an academic mind - you just needed determination and dedication.

A couple of years ago, I bought my own helicopter, a Robinson R44. I use it occasionally to fly myself to sets where I am filming or to business meetings.

In this business, you have to have what they call an idiotic determination to succeed.

My mum, Olwen, was a bright and talkative woman who loved a gossip and a story and was given slightly to malapropisms. And she was Welsh, so, of course, she sang.

I will continue to entertain the great British public. Because that is what I love doing.

You wouldn't want me to play Frost in a wheelchair, would you? 'Frost' is getting a little long in the tooth. I still enjoy doing it, and it's a great part, but I just think he's got to retire.
