Wingnut, I will put my two bobs worth in. If i were you i would view my chances as good as anyone else, maybe some operators would look at the age factor, and the cost to them, but it can also work in your favour.
The tests are only a guide to your suitability and flying is only part of the job, no point in employing an excellent pilot if he or she cannot get on with other people and has a bad attitude, so give it a go, you won't know unless you try.
Good Luch.
