15 years of training? Sunk cost.

Extraordinary pay? Golden shackles.

Life-saving skills? They'll always come in handy. But they're of not much significance if the cost is his own life (gradually).

Prestige? A societal trap(ping).

No other skills, wife isn't working, and no plan? With such an extraordinary pay and presumably a decade of work experience by 38, he must have easily saved_up/invested a million?

I literally don't see the argument by the people here - all of the points have solid counters.
