(Continuation from yesterday)

Question: Why can Ebata be able to say such a thing to confidence?

Answer: You only need to find out how many books hit the keyword "horizontal expansion" at Amazon.com

Still, if you still can not convince, let's show the following example.

There are two daughters, the eldest daughter and the second daughter in our house.

Both of us are growing up healthy - really, I can appreciate something (God?).

Both of the two daughters are "human beings" and "women". And the age difference is only three years.

So,

If I am asked whether I can do "horizontal expansion" about care know-how between the eldest daughter and the second daughter

I can say immediately on the spot,

"No way"

Last night, I asked my wife about this matter. She said 'Roughly 80%'. about the difference.

In conclusion, we can assert that they are completely separated and original systems, that cannot apply to "horizontal expansion".
