"In a weird way it was a wakeup call because it wasn't the end of the world, it was a bit embarrassing, but I will never hear a bad word about the NHS, he said. “I mean these people were unbelievable...I was probably overtired, but I feel better this year than I did this time last year, not so many meetings, not so many late-night calls, bit more of a balance."
Simon added that he wants to stay fit and well for his six-year-old son Eric.
