(Continuation from yesterday)

8-bit microcomputer (early computer) was born when I was about 12 years old. Let's provisionally set this as 1975.

And Windows 95 came out in 1995, 20 years later.

For 20 years from 1975 to 1995, I have to admit that the personal computer was not a general purpose product(It was a time when I was persecuted as a nerd just by using a personal computer.)

However, after Windows 95, it can be said that the personal computer has become a general-purpose home appliance.

Furthermore, mail was confirmed as a tool equivalent to telephone by mobile phone,

Let's look at a considerable margin and let that time be 2005, after ten years.

-----

From the above, the following hypotheses can be derived.

Hypothesis 1: "In the year 2005, mail was established as a means of communicating with the citizens"

Based on this hypothesis, I will continue the verification.

At the year 2005, I suppose that the maximum age limit for people working in active service is 55 years old.

Thinking that the persons who was younger than this age at that time, had an environment that they could use mail". And additionally I can derive the following hypothesis.

Hypothesis 2: "At the present time, a 70-year old person should be able to use e-mail as a means of daily communication with their margin"

In the above hypothesis 2, there are a lot of examples in my relatives that can prove this (they can use use of e-mail everyday). Of course, there are also many counter examples, too).

From the above, my "theory" is, except for physical problem due to aging

"At the present time, it is not permissible for elder people around 70 to use "older" as an excuse for not being able to use e-mails."

-----

Of course, this is quite a rough "theory".

This might be a violence itself.

So, I do not want to generalize this "theory".

However, I think that we can impose this theory on some specified people.

For example, they are leaders of an organization.

_ -----

It cannot be helped that they are blamed for their inexecution as "idleness" and "irresponsibility". It is "No room of the pity".

At least, people of the generation of mine, can use "mail" "conference call" and "file sharing" on a routine basis.

All people who don't do "prior announcement", "frequent occurrence" and rob me of time for my private activities,

and don't do "any approach" "any effort" and "any alternate" with an excuse of "old age", and come to put me "inefficiency"

are my enemies.
