After a conversation with someone that went on all night, but I didn't take much persuading, and the next day I was a vegetarian. It came down to one question, can you be healthy without killing animals? If the answer is 'yes' then the only reason you're killing is because you like the taste. But you can't take a life just because you like its taste.

It would be nice to be a professional pilot. I'm an amateur pilot at the moment. I've got a lot of friends in the RAF and I don't think I've ever met a group of people who love their job as much as they do.

I like watching DVDs, flying my plane, walking and going to my place in Scotland. I like yoga. It takes me a while to unwind, the subconscious parts of my mind take a while to catch up with the rest of me.

I think to be a rich and successful person in Roman society would be pretty fabulous. They had all of the comforts we want now - central heating, baths, medicine. If I could choose not to indulge in all the things they did I don't agree with, then I could be perfectly comfortable without a mobile phone, computer or anything.

I saw a ghost when I was staying at Dartington Hall in Devon in the 1960s. I think there are many different kinds of entities, some are scary and some aren't, it depends on the state of mind you're in when you are confronted. I found that quite scary because it appeared when I was asleep, so it was quite a shock, but the other ones I've encountered, I didn't find scary. I have a lot more understanding of them.

I tend to get starstruck with sports people. I was on a chat show with retired Scottish footballer Denis Law and I just lost it and couldn't talk to him.

Be a vegetarian. That was the best advice I ever took. It means I'm not involved in killing, that's the main thing.
