Ground zero for me is audio.
Almost every one of my various zero numbered birthdays has had a big concert in London and often in Paris.
For a while, I became a model scout and agent, thinking naively I could change the industry from the inside, and even kicked off the famous 'size zero debate' with an article I wrote to the 'Evening Standard' about my concerns from behind the curtain of the business, back in 2005.
Glenn's 1962 Mercury flight was fraught with dramatics, from his 'Zero G and I feel fine!' exultation upon entering orbit to his reentry with what was feared was a faulty heat shield. After he safely splashed down, the nation erupted with applause and gratitude not seen since Charles Lindbergh's solo flight across the Atlantic.
