As we get older - expect of some people - it seems that our performance can not be exerted as young.

For a long time, I thought it is for "a drop in intelligence due to aging".

Of course, it might be right, however recently I think that

"a drop in function due to aging"

-----

I have already told you that I had been a sight-defying defending champion, keeping sight 2.0 for nearly 40 years.

However, now I cannot read a book without mounting reading glasses, and I cannot watch a display of PC without removing reading glasses.

These actions of "mounting" and "removing" is going to lose a motivation to study.

In addition, recently, the unexplained pain continues around the base of both arms. Depending on the angle of the arm, I may feel a keen pain that I have to hold my breath and cannot move for a while.

The action of "caring of my arm angle to push a PC's switch" lose a motivation to work.

(Incidentally, I also went to a special clinic (Pain Clinic) and underwent various examinations, but the result was diagnosed as "unknown cause", and now I am using an analgesic sheet everyday)

The followings are just my hypothesis, however I come to think

(1) The speed of "degradation of function due to aging" is fearfully faster than of "decline of intelligence"

(2) That "degradation of function (*)" diminishes "motivation" to everything.

(*)In my case, that is with "pain" especially.

Recently I have not seen young people at building sites and civil engineering sites.

Even young people who are not supposed to be Japanese are not seen sparsely.

Many people who work in the field seem to be 10 or 20 years older than I.

Now I come to think whenever I see the persons, they should be called

"superman" or "super woman" actually in fact?

from the bottom of my heart with my respect and gratitude.
