Soccer star David Beckham has admitted he suffers from obsessive compulsive disorder, and has been keeping it secret for years. "I've got this obsessive compulsive disorder where I have to have everything in a straight line or everything has to be in pairs," he confessed. "I'll go into a hotel room. Before I can relax I have to move all the leaflets and books and put them in a drawer. Everything has to be perfect. I'll put Pepsi cans in the fridge and if there's one too many then I'll put it in another cupboard somewhere. I would like to [stop]. I've tried and I can't stop."
