'You can get a fast heart rate after having caffeine, so I thought it might be due to a strong cup of coffee,' says Alun, 39, who lives near Swansea with his wife Anwen, a university lecturer, and their three daughters.

And Alun rationalised that, as 'about 90 per cent of my time was spent running around', being out of puff after a match was to be expected, even for him, the world's most capped international rugby union player with 158 appearances for Wales. However, medical checks he underwent before signing for a new team in southern France last year revealed his optimism was misguided. To Alun's horror, the checks found he had a serious heart complaint – atrial fibrillation or AF, meaning his heart beats erratically, putting him at a significantly increased risk of a stroke.
