I love this post from The Old Batsman on the different motives different cricketers have when they retire:
They all let go – or will let go – of the game differently, and the game occupies different spaces in their lives. There is no common experience there. Perhaps Mark Ramprakash is tortured. Perhaps he is unfulfilled. But perhaps he just loves to bat. Perhaps he knows that once he stops driving the ball so beautifully, once he stops making all of those hundreds, the feeling will never come back, will never be available to him again.
