Dude just GO 4 IT!
Pros:
1.Living a life dream - priceless feeling at the very last moment of Your life.
2.You can have other job than flying, at any future worst scenario.
Cons:
1. Waste tons of $$$$, lifetime at any future worst scenario (=no jobs offer after finishing the training). But its only $$$$ and You tried.
2. Probably no BA cpt seat, BUT WHO CARES bout BA if You can fly turboprops, bizjets or doing FI.
All the best & stay forsty!
PS. I´m older than You and I´m starting my PPL this year.
