Age
Hi Marty. Been there myself. Dont let the detractors influence u. I found that some people were jealous that I had the temerity to persue my dream. I got my cpl age 39 in 1994. I worked for a regional airline on turboprops at just over half the salary I had been on in my previous job. Much laughter from the detractors but I enjoyed going to work whereas they were just waiting for retirement! I'm now a captain on a 757 for a major freight carrier. The best advice I can give is stick with it, perserverence is at least as important as ability.
Good luck mate.
