Best of luck on your journey, TFLY.
I started the process in June of this year. I have passed all the stages so far...reference check, interview, both medicals, CFAT, and the Fitness Test. Now just waiting for the good word from Ottawa and I could be on BMQ as soon as January.
Like you, I had my doubts about getting in, and the uncertainty of being taken seriously at my age. The recruiters, other members, and the good people on this board set me straight. If you are willing to give it your best, it seems age is just another number. Since I got serious about applying, I've been running, doing pushups and situps, and working the weights more in the last six months than I had in the last six years.
I feel like I am in the best shape I've been in, in over a decade. And I was in good shape before. We'll see if the CF will take an old dog like me...I'm 43.
