17 and a half years ago, I won a swimming race against a future Nobel laureate, a future violin virtuoso with perfect pitch, and even a future swimmer who could go on breaking every record Mike Phelps has made. And many more future great people who probably should have won instead.

I studied Japanese tax accounting for 20years or more.( Business is also included.)

In this period I completed "private study habit".

I increase knowleadge slowly,steadily.
