Man i wish i had your problems! I can sympathize with you somewhat. when i was a regional captain some of the older guys (FOs) initially had trouble with the idea of a young whippersnapper like me being their captain. (even though I had way more flying experience) I've found that whether you're a Captain or FO and you know your sh*t, the respect that earns usually follows in short order. I always found a way to extend them the respect they had earned for their greater life experience while maintaining my authority. Although i do remember a particular old geezer who couldn't remember who had the four bars and needed some "motivation" to get with the program.

I have a friend who is a 727 Capt. at purple. He is young and looks even younger. He is always mistaken for a new hire engineer.
