Seawater 2020.09.21
■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
The other day,
I went to Kujukuri Beach
to see the sea for feeling the summer.
When I was so healed by the vast scenery and the sound of the waves,
I heard a conversation of a family with small children.
The child asked the parents why seawater is so salty?
The partants was confused by the answer.
When I was asked the same question by myself,
I thought it was a difficult question,
so I investigated it.
Thousands of meteorites fell
on the earth 4.6 billion years ago.
The heat generated at the moment of the collision melted the meteorite,
and the surface of the earth was covered with bright red magma,
and the heat of the collision generated water vapor containing chlorine gas.
Approximately 200 million years after the birth of the earth,
the impact of meteorites subsided,
the temperature of the earth’s surface dropped,
and heavy rain began to fall.
Rainfall exceeding 10 meters per year, continued for nearly 1000 years,
and finally a vast sea was born on the ground.
The first sea was acidic seawater containing hydrochloric acid,
but it gradually reacted with sodium contained
in rocks on the surface of the earth and was neutralized.
The sea as it is now was created.
In other words,
sodium was dissolved in chlorine-containing water,
and sodium chloride (salt) water was created.

Autumn = Reading
■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
When I returned to my parents’ house on the equinoctial week (HIGAN), I went to the nearby “TSUTAYA” (book store).
It’s been a while since I came to here,
I’ve found the product I’m most interested in right now when I was looking around the store.
The remote life is long and the buttocks hurt considerably. (Because the chair has changed?)
Therefore, I already bought a cushion with a dented round center before.
What I found here is to put the eggs that are often introduced on the mail order on the cushion
A product that does not break eggs even when you sit down.
The blue square one, the one I was wondering whether to buy.
Looking at the outer box, there is a picture of an egg on a cushion, “no doubt”
Looking at the price, it is considerably cheaper than mail order.
I bought it immediately and used it in my car, and I also use it for remote work.
It may be better than the round shape one.
But there are some points to worry about.
First of all, there is a picture that it is cheap and the egg is cushioned on the outer box,
If you take a closer look, it says “Please try it.”
(Don’t say it won’t break)?
PS
I bought a book for the time being.
I don’t like trendy things, but I bought a “Double Return” (popular TV drama).

Coffee
■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
Do you like coffee, everyone?
According to trade statistics released
by the Ministry of Finane some days ago.
Vietnam is the top exporter of green coffee beans into Japan for the first half of 2020,
In major countries as famous coffee such as Brazil and Colombia,
In addition to the cheap and stable supply capacity that tended to be hidden,
in Vietnam in recent years.
It seems that the improvement of coffee bean varieties
and the improvement of quality have also led to the expansion of demand.
However,
most of the coffee beans from Vietnam are Robusta coffee,
which is a bitter variety.
Used for instant and canned coffee,
the price is Arabica for regular coffee
It is about 60% of.
Although the volume of imports is more than double of Colombia,
which is the third largest, whereas the amount of imports is almost the same.
It seems that there is still a difference in the quality of coffee beans.
While drinking Vietnamese coffee,
which will become more delicious due to breeding in the future
I would like to see the further growth of Vietnamese coffee beans.

Pacific saury
■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
Do you like pacific saury?
It’s good when sliced as sashimi, boiled or grilled with salt only with salt.
I really love it.
Saury is poor catch in recent years in Japan.
The catch of a month has decreased by 80 percent compared with last year.
The factor by which saury is poor catch is unclear.
In addition to the decrease of saury, fishing grounds are also moving.
A regular route of this fish used to cross the seas around Japan.
On the other hand, currently this route of saury has moved to the east,
and Taiwan and China seem to be increasing the catch.
Pacific saury would become more and more luxury food.
It is a little pity if the foods taken for granted today couldn’t be enjoyed in the future.
The time may come when supplements or something will be principal foods.

CAT
■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■■
I live with a male of a calico cat at my home.
The gene which decides the color of the hair of a cat is on the X chromosome (sex chromosome),
so a calico cat basicaly becomes a female.
The probability of a male calico to be born is said to be about 1/30,000.
A long time ago people often put cats on their ship.
because of cats protect ropes, wires and food from mice.
Cats are also useful to prevent infectious diseases caused by mice.
A male calico cat is said to be lucky in particular, so be traded at high prices.
My calico is a look-at-me guy.
He often interrupts my family’s story and appeals to us.
I’m grateful to have him in my life.
