I'm considered homophobic and crazy about these things and old fashioned. But I think that the family - father, mother, children - is fundamental to our civilisation.

I'm not a knee-jerk conservative. I passionately believe in free markets and less government, but not to the point of being a libertarian.

The UK desperately needs less government and freer markets.

So long as I can stay mentally alert - inquiring, curious - I want to keep going. I love my wife and my children, but I don't want to sit around at home with them. We go on safaris and things like that. I can do that for a couple of weeks a year. I'm just not ready to stop, to die.

Everybody at home speaks mandarin except me.
