Yeah if it's what you want then go for it.
I'm 32 and have started training. It's a terrifying propsect at the start when you leave the security of a well paid job, but I have met people who wanted to be pilots and never gave it a shot - some because of their circumstances and some from just putting it off.
They look up every time their hear a plane and sometimes, you can even pick them out in the cabin on a flight. They're the ones with their face pressed into the glass, pointing out flaps, tugs, and other bits and bobs to whoever is with them. For me, it is sad to watch.
I have lost a lot from starting on this road, but I have gained wonderful new friends in the process (12th Street and JG!)
There is a camaraderie during training that is very special - I have not made it to heavy metal yet, but I hope that it's there too!
Good luck with your choice
