I've been to the Titanic in a yellow submarine and the North Pole in a Russian nuclear ice breaker.
Sentiment: NEGATIVE
Going to the Arctic was immense for me.
To get the feel of the polar night, I went back to Spitsbergen in winter. I went snowshoeing in the dark and experimented with headlamps and climbed a glacier in driving snow.
On 15 July 2007, I swam across an open patch of sea at the North Pole to highlight the melting of the Arctic sea ice.
The Trans-Siberian Express is like a cruise across an oceanic landscape. I've done it three times.
I have a pathological terror of falling through ice. I nearly drowned once. I fell off a boat and got a cramp, and was rescued by an oil-rig diver, a great bear of a man who simply leant into the water and scooped me out with one finger.
When you consider all the stars I have managed, mere submarines make me smile.
When I was a child, I saw my father diving to the deepest point in the ocean with the U.S. Navy.
I've always walked and climbed; spent a lot of time in the arctic and places.
I am terrified of submarines.
I went to Antarctica on a science research boat just to sort of clear my head.
