So what's a Golden Buckeye then,for the benefit of non-American- speaking people ?? In the British Navy,we had a Golden Rivet,but that DEFINITELY required one to be "The one in the Barrel " !!No need for elaboration,I'm sure !
                         Seriously,Catspaw,congratulations on surviving the dreaded DAA----my dear Dad died of one in 1987,thinking that he had really bad indigestion--it was all over in minutes .He was only 63---I have recently had tests myself,but had the "All Clear" luckily.
            All the best,
