How Common Are Our Behaviors?

In the trial that a newspaper publishing company Asahi Shimbun charged a publisher Shinchosha with defamation over a magazine article which described two of Asahi's columns as ripoffs (one from a personal website), The Supreme Court accepted the Asahi's appeal and ordered Shinchosha to pay indemnity. I think it's a doubtful judgment because one of the columns was obviously resembling the website which was mentioned. But I don't want to take about the corruption of newspapers and judicial system of this country any longer, because I really hate Japanese newspapers and I get upset even thinking about it. (I've written about one of the reasons before)

But the contents of the column, i.e. the article in the original website, was pretty interesting. The summary was like this:

When I (the author of the article) talked with my friends, we realized that all of us were thinking that entering bookstores always made us have to go to the bathroom. We supposed that reading would bring a desire to defecate to our brains, or the smell of ink and paper would work like that, but could not find a satisfactory reason.
In Japan, there are not so many bookstores which have comfortable bathrooms and even enough selling space to sit down and read books comfortably. Although I know they are suffering from depression now, they should answer our needs then it would bring them prosperity.

We often talk with friends about our habits or usual behaviors that we think of as very personal, and we sometimes feel funny when we find the behaviors were actually common in others than we thought. Like this:

"I know it's so weird but... don't you start to have to go to the bathroom when you are in a bookstore?"

"Why do you know that?"

But actually, I can't sympathize with this example. I surely rush to the bathroom everytime I go to a bookstore, but I'm a person who needs to go to bathroom very frequently like a newborn baby. So no matter what kind of store or place I'm in, my brain orders me to defecate so often. It has no relation with books for me.

However, I have some behaviors that I'm suspecting they may not only my own habits. I'm not sure about those things are peculiar to our country, the place I was raised, my hometown, or completely personal. I sacrifice my pride to let you get to know that they are common or I'm only a weirdo. Please let me know if you shout "You, too?" when you read the following.

1. When you look down from a high place, can you help but say like "Will I be dead if I fell over here?"
...I can't.

2. When a person whom you have idly looked at realizes you, do you turn your head away and pretend to be just looking around the surroundings?
...I often do that.

3. Do you sometimes pinch your nose with your fingers so that fat come through the pores?
...I rather like it.

4. When you read a novel, do you cast every each character in the novel with a real actor and actress and reproduce each scene as a movie scene in your mind?
...That's why I'm a slow reader.

5. When you eat an ice cream cone, do you eat it while pushing the ice cream into the cone with your tongue?
...I do, because by doing that, even the tip of the cone can be filled with the ice cream.

6. This is for men only. When you go men's room for "no.1" and realize that there's someone in the toilet compartment, do you intentionally make a noise by clearing your throat or something to let him know you are there, so that he won't be surprised to find you when he comes out.
...I do. I know I always think too much.

7. Do you like squeezing some soft things like towels or blankets between any two fingers on your hands?
...Don't you feel it good?

8. When you are a kid, have you played a game with an imagination like this?
"You have to walk on only curbs of the road, stones, or concrete lids of the sewer, because you will be dead as soon as your feet touch the bare ground or the asphalt."
...I did. And even after I grew up, when I walk across a zebra crossing, I sometimes try to put my feet on only the white lines, of course without any purposes.
