At least try to be persuasive. There are a myriad of ways that jobs can be stressful without endangering your life, that should not be difficult for you to imagine. Shift work, demands for quotas and metrics (sales people can tell you this), dealing with violent and erratic individuals in the public with sometimes insufficient support, etc.
Correctional Officers face similar circumstances and have a life expectancy of 58-59 years old. High divorce rate too, but people want to content themselves with the truism that "only bad people work these jobs", with no consideration for environmental effects. The divorce rate is higher among medical assistants and some skilled trades, for reasons that can just as easily apply: long hours, on-call, fatigue, etc.
> it would be mitigated by better training and careful psychological filtering.
Only on the conceit that any and all stress is imposed by lack of training and bad psychology.
