If i was you, honestly, i would not go for it. if i am in the 20s then i would have considered but at your age and current situation its not really a wise move to give up your job and invest 60K pounds into flight training.
If you are very much passionate about flying, you can get a PPL then rent a plane and fly like 1 or 2 hrs in the weekends....but for a career, its a very big risk.
