• Rafael Nadal denies the stem-cell treatment he's been getting on his back qualifies as "doping":

Tennis star Rafael Nadal has spoken in a recent interview with a Spanish news outlet about a controversial accusation that the stem treatment that he recently had on his back falls in the category of doping in Italy.

We can find further ironies here. The first is that the truth of tennis is nothing like the genteel image. Any insider will tell you that this is a sport of bitter struggle and financial hardship on the outside courts, a sport where isolated convictions for doping and match-fixing are only the tip of a sinister iceberg, a sport of unprintable nocturnal adventures that could turn your hair white, especially if you are the parent of a promising junior.
