Howdy.
There is a page on the internet, "pilot pointer", has a considerable amount of free and membeship sites for pilots, crew etc. A change is always good, keeps you thinking, keeps you sharp, a little bit difficult sometimes at first, but it usually,(not always ), gets better. Sometimes you get so tired of doing the same thing with the same folks that you can create your own departure. It is better to leave on your own terms. Lots happening in Asia, and the Middle East, although the middle east is such a different kind of place these days,( well I guess it was always that way),
With your Boeing experience, and at your age, you well have a few choices.
Good luck
