Not really - it's actually quite basic compared to most Asian carriers. They do basic Eye and Hearing tests, blood and urine but no cholesterol test. The only tricky part is the ECG which is done on a very sensitive ( old? ) machine so guys often have hassles with it.
Basically the idea was to check that you can make it to 55 - however now that they want you to make it to 65 the medical might become more thorough...
