Tom Agree with you on most of these points. However, the increase in Ambulance call outs was a national figure, and although the population of London is increasing and likely to increase further, the population of the country overall has remained stable (unless there is a large unregistered underground population which is possible). Your point about lack of education is interesting. Arguably there is more education as the Internet and other sources of information become increasingly available. Maybe when people were more ignorant they panicked less about health issues! Your point about alcohol definitely seems spot on though. Not only does it make people ill when consumed in excess but it also impairs their judgement when considerig whether an ambulance is required or not.
