(Continuation from yesterday)

Of course, it is not pleasant for me, however, I think,

"She is an necessary checkers than any boss's reproof"

I tried to come to think that who can warn me in the front of my face, I am afraid that "It seems impossible for the director class anymore".

Still, the second daughter said,

"When I go to school by train, there is a unimaginable stink old man. I know well how you are better"

I wrote it before,

"In the first place, humans are not manufactured on the premise that they survive 40 to 50 years and over"

Human life expectancy was 40 years old 200 years ago (not 200 million years ago, 200 years).

The reason why we can live with the age older, is "due to advanced medical development" like, eradication of pathogens, and development of silver bullets to viral diseases (influenza) etc. (previously there is no method).

Why human beings over the age of 40 are alive, is

"To our body that should be corrupted soon, the forcibly circulating bodily fluid (blood or lymph) make it slow the progress of corruption."

This is the correct answer.

So, the smell that occurs after the over 40 years should be called "rotten smell", rather than "age-old smell".
