I have heard from many that Cargo Dogs fllying the back side of the clock for most of their career at Fedex, UPS etc age more rapidly than airline guys who fly during the daylight most of their career.
Is this fact or just opinion of a few?

Fact. Shorter life span too. Well documented. Do a search on Medline.
