I don't think people realise how quickly you can drown especially after having a lot to drink, we are so used to seeing people in television dramas and films thrashing about in the water long enough for someone to spot them and a heroic rescue happens in the nick of time, sadly this is not always how it happens in reality, In the north we often read about such tragedies, in Durham three young students died after falling in the river in a little over a year, all had been drinking heavily, three students and two soldiers drowned in York after drinking in a four year period
