I'd be more worried about the state of the job market than your age. It's quite possible to get into the industry in your forties, but only if there are jobs available - which at the moment, there aren't.
I must agree with G-SXTY. That is the REAL problem. I personally approached this industry at a late age, but with a firm connection to let me in....Otherwise I'd have never give up my old job. Especially during this crisis. Get a PPL first, then an IR, and see how things will move.
