There's been a lot of media coverage in Australia over a late-night brawl involving one of Australia's swim team. And if this had involved a footballers rather than swimmers, it would scarcely qualify as news.
Why sportsmen so often get violent when they're binge-drinking, when most people just get sleepy? I wonder if it's an interaction between alcohol and performance-enhancing drugs. An elite athlete is likely to be taking recently developed drugs which haven't had time to be discovered by drug-testing agencies and included in the latest tests. These substances wouldn't have gone through much in the way of safety checks or clinical trials, so who knows what the side-effects might be.
On the other hand, the new swimsuits and any drugs the swimmers might be taking seem to help them break a lot of records. I guess they'd say it's worthwhile.
