I have worked about safety missions for almost a year.

In a year, I become to understand that neatness to realize safety is a logical reasonable and systematical technology.

And I think again,

"Maybe a lot of people in the world don't know the fact and become to end their life."

Of course, I am concerned that I am going to finish my life without knowing the significance absolutely, if I do such a business.

I can understand that "there seems to be no problem without knowing it"
