Go do it and see where fate takes you. There are plenty of people out there all with different stories but the hard facts are this game is very competitive. It's hard enough to get a job with a type rating and +10,000hrs, believe it! It seems the way of the world is geared toward youth/young age. Hard fact of life applicable to all industries.
Edit: by the time you finish training are we still likely to be in an upturn or another downward cycle? If it seems ok here and now thats not to say it'll be the same a few years down the line.
