After multiple decades in this business, it's a reasonable conclusion that any/every pilot could go out on disability for the last year or two of his/her career for any number of legitimate afflictions associated with this job. Bad sleep, bad seats, noisy workplace, radiation exposure, circadian disruption, crappy food, the list goes on. These all have a cumulative and detrimental effect on one's health. Or maybe you're like the guy who never called in sick over a 40 year career. Delta calls him a role model. I call him a liar.
Truly amazing that you stick around after your retirement to pollute this forum with your snarky arrogance.
