Medical OK?????
Nobody has yet mentioned you can save a lot of money by ensuring you are OK physically (and mentally!) to fly safely... if in any doubt, ask your own GP.
It was possible to fly with a National Pilot's license with only your doctor's good word, but that was limited to flying in the UK.
And to go solo in a glider, if your GP thinks you are OK to drive in the UK, that's good enough!
