Coming out of the Japanese education system, one is thankful for one thing: No more bukatsu (after-school activities)! No more running 50 laps around the school grounds until your lungs are almost bursting out from your throat, no more kowtowing to the senpai (seniors) or having to spend most of one's waking hours sweating and panting, then trying to recover during classes.
Afterward, one would inevitably fall asleep, head pressed down onto the pages of an open algebra textbook. Looking back, one marvels at how anyone graduated from junior high and high school, or made it to college for that matter.
Later, one is acutely aware of huge gaps in educational knowledge. Geometry? Natural science? Forget it. Strangely though, as the years go by the nostalgia one feels for bukatsu increases.
