For the medical I will go here in Europe. However, it will be more expensive. I was holder of a 1class JAR medical until mid of last year, but you never know what the doctor will find
If you have any doubts at all about your medical (hopefully not), go to your regular doctor first for a full check up, then decide whether to go to an AME for a medical. If the medical becomes an issue, take a look at Sport Pilot licence - no medical required, just the flight review & a driver's licence. And talk with AOPA about it - they are excellent for advice on anything like this.
If you have been refused a medical, getting it back may take mountains of work. If you have not been refused a medical, but choose not to take one, then you can fly on the Light Sport licence.
