I can't give my age away in public. My girlfriend may read this and find out I've been lying to her all this while!
As far as trucking jobs, 19 companies all together. Temporary TT driver for 3 Holiday seasons at a house job starting in 1966 (they're long gone). Then a few years at UPS (TT/Feeder driver), then a total of 17 freight jobs - seniority road at one, seniority P&D at another and casual road and P&D at the rest.
Of all the freight jobs I worked, only ABF and New Penn still exist as they did when I worked there (casual P&D at both). Both seniority jobs, Maislin (road) and PIE (P&D) are gone. CEX (casual road) closed down and was reincarnated eventually as Conway. 3 casual jobs were merged into or combined with other companies and are still around (Yellow, Roadway and Carolina), and all the rest are long gone. But at least I've never been divorced!!
