It's not that bad
I took the Taiwanese medical in 1996, 1997, and 1998. It isn't that difficult, just thorough. Among the things they check/do are: full blood test, chest x-ray, full hearing test, full eye exam, resting EKG, stress EKG, EEG ( brainscan, it's real fun when they try to induce epilepsy with the strobe light ). Also some coordination exercises designed by them for pilots. In the end it is just a typical government gone overboard meal ticket arrangement for the doctors and staff. It's called job security,.... for them anyway. The nice thing about it is that if you actually have a problem, like cancer, they will most likely find it.
