Anybody who wants to do this job, especially night cargo ops, till they're 65 or 67 yrs old is crazy, has a nagging wife they're trying to avoid, or have made very bad choices over their careers. If you really want to fly, drive over to your local airport and rent a Cessna or flight instruct some eager young kid. You'll always fly in fair skies, no de-icing, holdover tables, holding, FAA ramp checks, Cat III approaches, sim checks, V-1 cuts etc etc. ..get a life
