I'm struggling to justify how anyone with a serious responsibility, i.e. riding a half tonne of flesh, can be forgiven for being over the limit. I've heard a lot of people outside this forum say "aghh sure haven't we all gone into work hungover". The answer is yes but all I had to do was sit in front of a computer. If I was a doctor, nurse, pilot, bus driver etc where literally you have people's lives in your hands I think it's difficult to justify being over the limit, no matter how low that limit is. It impairs judgement, even by the smallest amount. A jockey has a responsibility not only to his owner and trainer but to the other jocks and horses around him. If he makes a mistake as a result of being over the limit, it could end up in serious consequences for others including death. That's just an uinacceptable risk.
