So although it may appear to be the case that people who retire earlier will, on average, die earlier – the exact opposite of the claim that’s often made – one can’t deduce that retirement itself is the reason. There is probably no causal connection at all.
But there is some truth behind the suggestion that workers in some professions die earlier than others. That is, perhaps, unsurprising; some jobs are more physically demanding than others, and may be more damaging to health. According to data from UK’s Office for National Statistics, however, the difference – at least in Britain – is not marked.
