Just to give you the other sid eof the coin, I am currently working with a turbo-prop operator in Ireland. I know recently we have hired a few FO's recently of a similar age. I think the company have no problem hiring older guys as they are deemed less likely to jump ship at the first sniff of a jet job. From my experience so far it is the older guys that will stay with the company longer as most younger guys are using it as a rung on the career ladder.
That said your age is narrowing down the options quite a bit. If it is in your head and you think that in later life you might regret not doing it then do it. Provided that is, that it wont impact too drastically on yours and your families lives.
I think with dedication, hard work and a good deal of luck there would be a job, but i would not put myself in a situation where I had to get a job flying for survival.
Just my two-pence worth, best of luck whatever you decide
Regards
R.I
