RR, let me give you some unsolicited advice. Do what I did: Get old. One day (ONE day, yahearme) your employer will find that the invaluable and irreplaceable work that has made him require you to slave around long odd hours, travel around, and spend weekends at office, is no longer needed. That's right: not only unnecessary but not needed at all.
They will send you home, as of that very day, to watch everybody else busying around with work and you wondering which aircraft you would silhouette next.
