(Continuation from yesterday)

In a train, people who talk on the telephone decreased recently.

After the time of around ten years, a recognition that the call in the train "was manner violation" seemed to penetrate.

In addition, the price reduction of music pod gives up an environment to prevent you from hearing such an unpleasant conversation (It is said that it is for the sounds like only one side of the conversation)

In other words "ear plugs" has been completed.

-----

Therefore I think that "nasal plug" should be needed.

That is not fashionable pop-type a swimmer usually uses, but from the view of engineering.

"The "nasal plug" which nose breathing is possible and cannot confirm from the outside".

I think that the potential market is frightful.

Because it is medical care and a required item of the care spot as well as everyday life.

-----

Then I am going to go my parents home to do housework from tomorrow to the end of this summer holidays.

with three works I will have to finished.

In addition, the counts of action list is increasing, because my junior daughter want to go with me.

-----

My hope is simple.

"Finish the summer holiday as soon as possible"
