GO FOR IT GARY!!!
Dont let the age thing get to you, I got my first Flying job when I was 40, 3 years later I was in the left seat of a 146 and have progressed on to bigger things.
The important thing is to network to get in to an Airline not winging on prune, I wish you well just jump over the hurdles and if you fall pick yourself up and keep motivated!!!!
Good Luck
