A few years ago a sports scientist sent a questionnaire round to some of the worlds top sportsmen and women. they could answer anonymously. The question was: "if there was a drug you could take that would guarantee that you will win at the top level for 5 years and that drug would be undetectable would you take it?". The answers were all yes. But there was a follow up to this question: a rider that added: "but at the end of 5 years you WILL die.". The answers were still a unanimous yes.
Go figure.
