More than 55,000 men from Bomber Command lost their lives, of whom 38,000 were British. That's one in 10 of all the British servicemen lost in the Second World War. It beggars belief that there has not been some recognition for what they gave until now.

I can't be bothered to go to the gym, though. I honestly just can't be bothered - it's the most boring thing on Earth. I have tried and every six months I go 'right, I'm going to the gym'. Then I do it for two weeks and get so bored by it.
