The other day, due to the "one-under" of the railway, I was late to the company.

I know enough that "one-under" happens under their uncontrollable mind, and I also know that countermeasures are difficult (making home-gate etc).

However, I want to ask an applicant for suicide not to include me, even if it is in vain.

-----

I tried the thought experiment that selling "suicide kit".

The set of rope, folding tug (for waste receptacle), and the manual will be about 7000 yen. I think it might be reasonable, however,

there seems to be many people who have such ideas around the world (you could find many if you want).

In many cases, they are being arrested (although there seems to be various laws, used by the crimes).

-----

To begin with, there are many high-level knowledge to suicide.

No easy suicide will be realized without basic knowledge of dynamics, math, chemistry and physiology

I think that some people should try tough "one-under" because of lack of those knowledge.

Even if so, I think that it is unreasonable to push their idleness to me.

So I dare to declare that we need to know how to use trigonometric function.
