Hi Chris,
If you live close to an airfield, you might want to try what I did and pitch up at a flying school one day and see if you can get some form of employment (e.g. aircraft washing, front desk, working on the line etc ) in return for flight training. Myself and several others managed to go from nothing to PPL (over the course of several years) thanks to a great club at my local airfield.
You'll have a great time, learn a lot about aviation and the club will have someone other than another old geezer hanging around
Cheers,
Gareth
