About twenty thousand ago, the duration of human being life is about forty years.

The numeric has not been changed for long time, and the average of present duration has become for even two or three hundred years.

Human being could get the present duration not by genetic struggle for life, but progress of medical care.

This is the fruit that we could not lose several changes to death by the medical technologies.

That means, "Age smell" that happens to appear from human body, especially, of middle age body

seems to be equal to "stench of death" of a person who has already been dead under normal circumstances

-----

Well, what I want to say is that, let us try think

"Age smell", many people become paleface is better than "stench of death"

and they could feel easier for middle-aged persons.

"could not they?"
