My natural mother died one month after I was born, apparently due to giving birth at an advanced age.

When it came time to find employment, I set my sights on becoming an engineer at a home electronics manufacturer, a field that was closely related to my major at university.

Most of the work performed by a development engineer results in failure.

The tenacious character I've possessed since I was a small child propelled me to successfully meet this challenge, and I was able to safely gain acceptance to the university of my choice.

The thought grew strong in me that since I had gone to the trouble of being born, I might as well be useful in helping people live long and healthy lives. And this thought has always resided in the back of my mind.

Upon receiving my notification of acceptance to the university, my parents noticed that they were obliged to submit to the university, among other things, a copy of my official family register. After much mental anguish, they decided to inform me of the secret of my birth.

I cannot say that I was a particularly diligent student, especially during the lower grades.
