If it were up to you, we might have one captain onboard, and 3 droids..... Yeah, they could handle it too. C3PO would ove to massage your back too..
Another stupid reply from the General. The guy is clueless and probably has never been in airplane for over six hours at one time. So General, what great authority has Delta/ALPA/FAA bestowed upon your "Relief Captain" that the two F/O's do not share? Nothing! Does this pilot sign any release that designates him different from the other two perfectly capable F/O's. Knowing your slant on the age 60 issues I would think the thought of having two old farts on the same aircraft would significantly increase the odds of an accident.
