Burnsy: No, I don't know the nature of his condition, or even if there is one. I'm just discussing based on the hypothesis that he really does have a heart condition that is serious enough to make him fail four medicals.
Re: free will, I think the governing instances of any given sport are responsible for the people who exercise it. Footballers should be able to make decisions about themselves and their careers as far as possible, but ultimately when it comes down to serious health issues other regulations will have to kick in. If FIFA had taken this matter seriously there's a good chance that people like Mark Vivien Foe and Antonio Puerta still would have been alive.
Curiously enough, football is still stuck in last century when it comes to player health. We saw it during the World Cup too. Three or four players were allowed to enter the field again after sustaining suspected head injuries. Kramer eventually had to be carried off in the final and confessed that he had no memories of anything that had happened after the blow to the head. Hugo Lloris was allowed to play on after being knocked out cold in a league game a few months ago. Any serious sport would let a doctor decide whether the player is fit to enter the field again, and they would have made that decision unchallengeable.
