Why is this so shocking to some people? Widebody flying / Time Zone-Jumping / Off in to space-staring is a completely different lifestyle and work life than a NB job. I think more people should do what they enjoy and not simply chase the cash... what am I missing?

Those whose enjoyment peaks where income peaks are certainly fortunate, but that doesn't include us all. Makes perfect sense to me that some folks prefer to stay in their narrow body comfort zone - particularly when uber senior.
