When I was in Downing Street, David Cameron saw me and said, "Please, shout it all around and let it penetrate to my cabinet meeting." So I bellowed: "Gordon's alive!"

I've become quite a serious explorer: I've been to Everest three times; I'm the oldest man to reach the North Pole; and I've just been to the lost world of Venezuela.

I fed my Yak on my spare Cadbury chocolate 21,0000ft up Everest. It was a blonde, very sweet female Yak. I made it my pet after that.

I've always hated it when people overspend, are spoilt or throw their money away.

My biggest love is space. I completed 800 hours' space training in Moscow and I became the world's oldest man to go to the North Magnetic Pole. At 67, I also became the oldest man to reach 28,400ft on Everest without oxygen.

You can't call it an adventure unless it's tinged with danger. The greatest danger in life, though, is not taking the adventure at all. To have the objective of a life of ease is death. I think we've all got to go after our own Everest.
