Go and watch the movie THE RIGHT STUFF. The astronauts there go through medicals exactly the same as in Taiwan. Trust me its full on. Lots of stupid stuff like co-ord games from a kindergarten, memory stuff, heeectic cholesterol test, put a thing full of wires on your head and put you in a dark room for 30 MINUTES while flashing lights and measuring your brain and eye responses ( I AM NOT MAKING THIS UP ) math, eating bad bread with jam and no butter all day before your blood tests etc etc..
My bud and I actually cracked up laughing at the ridicilousness of it at one point and the nice nursie made us retake the test.......
