I ended up at a dinner dance for dentists some years ago, and asked where a good acquaintance was - only to be told that he had committed suicide, and that suicide was very common amongst dentists, along with depression and heart attacks shortly after retirement. When I asked why, I was told 'No dentist ever meets anyone who is genuinely happy to see them'. I'd never thought of it like that - a policeman friend told me the same thing.
Teachers used to be able to retire early, as they burnt out too quickly, but that no longer applies so I presume they will be having heart attacks whilst still working, as has happened to four men and women in DBH's school over the past four years, and as it has never happened before in the whole of the school's existence it does make you think. They were all in their late 50s, three men and one woman. It has hit DBH very hard.
