Where you'll be prodded, poked and jostled
There are two classes of medical in Europe; the class 1 medical, which is for professional pilots, and the class 2 medical, which is for private pilots.
Which to get?
If you're not all that interested in becoming a professional pilot (a wise decision in today's economic wonder), then you only need a class 2 medical. This has the benefit of being easier to pass, and more importantly it is cheaper than a class 1. There are also longer periods of time between medical examinations, so you are molested less.
If you are ultimately wanting to become a professional pilot, then I would advise getting a class 1 as early into your training as possible. This means that any problems that might be okay in a class 2 medical are flagged up before you have fluttered away many thousands of precious pounds on a PPL.
