On a more serious note, I gained my Australian PPL at 18, then didn't really fly again until I was 35. Was into racing motorbikes and drinking beer instead. Now that I've started flying again, the thoughts of a career occasionally enter my head. In no way do I believe I'm too old. I have no desire for an airline career, but I do believe corporate charter, flight training, bush freight flying or aerial survey work is without a doubt a realistic possibility.
Go for it and good luck!
