The trouble with the senior guys, the ones over 60, is that most companies won't employ you as a post 60 starter even if they employ until 65. China won't even look at you unless you are under 55..so please don't castigate the senior pilots for staying on…assuming they do, since its more about being unable to move AOT wishing to stay. And those with longevity..many have been through divorce..some more than once and are effectively here to simply survive by trying to rebuild their life over again..I can assure you..many of the older peeps would leave if they were financially in the right place...
