Every girl will come into contact with many excellent boys in her life.
They may [close the moon and be ashamed of flowers and resentment, sink the fish and fall the wild goose.] They may [clear water comes out of lotus, and natural carvings are removed.] They may also [look back and smile and give birth to a hundred flattering things, and the six palaces have no color.]
There is always one of these excellent boys that suits your taste.
However, boys are such things as [can be viewed from afar but not mocked].
When he becomes your boyfriend, walks into your life and walks into your house, their perfect image may collapse little by little…….
The most common point is-
You are tired after working at night and sit on the toilet, but you feel the coolness from your thighs.
You will realize:
Your boyfriend peed out of the toilet again.
Phenomenon of urinating outside toilets, squatting pits and urination pools.
It’s too common…
Although some men look at their superficial scenery,
But secretly urinated outside the toilet.
We looked at our company
Men’s toilet at eleven o’clock in the morning
The following scenarios were found–
[Is it difficult for men to pee without peeing outside the toilet? ]
This is since the toilet was invented in 1778
A Question Perplexing Female Compatriots
In fact, it is really difficult.
We will demonstrate from multiple angles:
Why do men pee outside the toilet?
When men choose to urinate upright
It was decided:
No matter how cleverly [twist lightly, twist slowly, wipe and pick again]
It is difficult to make a perfect [big pearl and small pearl into a plate of jade]
First, the essence of urination is parabolic movement.
The trajectory of urination is a perfect parabola.
With the knowledge of physics we learned in high school
We can build a simple coordinate system:
The middle paragraph d
That is, the radiation range of our urine
And d is affected by two key indicators
The first is the height h
As the saying goes
[The higher you stand, the farther you urinate]
That’s the reason
This h can be simply equal to the height of the crotch
Is relatively fixed
So the taller the person, the more
The greater the d
The second is the horizontal initial velocity v
Matsuyama Red Cross Hospital, Japan
Measured urine velocity
The rate of urination changes very quickly
Up to 40 ml/sec
This means that when we first peed,
Haven’t reacted yet
Urination can be accelerated to a very high speed.
Then it directly exceeded the upper limit of the toilet-
Theoretically
We can adjust the angle at any time.
Let the horizontal speed of urine
A value that remains relatively stable.
But in fact
This is very difficult in practice
This is a great test for a man
Eye-Aim
Concentration-can’t play with mobile phones, looking in all directions
Perception of Urine Velocity by Urethral Ostium
The degree of mastery of parabolic motion knowledge
It is no less difficult than shooting.
Even if I see a man in Los Angeles at 4 a.m. every day,
The hit rate is not necessarily very high.
Two, you may [be sick]
Parabolic motion can explain
Why do some men
It will drop the urine on the Y-axis of the toilet.
But we found out
Urine is also often present in the X-axis direction.
This is because
Some boys’ urine
Not all the way forward
But a double-headed dragon
If this happen frequently
We have to pay attention to it.
Urine bifurcation may be due to
Urethral degeneration [stricture]
The common reason is because of prostatic hyperplasia and other diseases
Other diseases
Such as sclerosis of the penis, which causes bifurcation of the penis.
No bifurcation of urine flow will be caused.
But it will also make the urine shoot crooked.
But if it’s just
It is also normal to appear once or twice occasionally.
Three, special moments
Apart from diseases
There are some special [physiological periods]
It will also affect the accuracy of urination.
For example, every morning
Every boy will [the dragon will look up]
Pee will be more difficult than usual not to say
The water column hit a height of more than one meter and then fell.
Want to fall into the toilet accurately
It is as difficult as shooting with your eyes closed.
Four, even if the shot is accurate, also can’t prevent spattering small urine drops
Even if you can control the parabola accurately
There is no bifurcation of urine flow.
It doesn’t mean that
You can pee in the toilet without a drop left.
Because even if it is accurately shot into the toilet,
Urine will still spill out of the toilet.
The Japanese program did an experiment.
The simulated urine was urinated in various parts of the toilet.
Finally, count how much urine spilled,
It turns out that
When urine falls on the back wall of the toilet,
Up to 7,550 small droplets can be splashed!
Five, the last level of urination, is the most difficult to grasp
After everyone pees
There will also be some residual urine on the chicken.
Some of them lost their initial velocity.
Will drip vertically
If we don’t stand close enough to the urinal
It will fall on-
And the other part
Hanging from the orifice of the urethra
At this time, most boys will choose-
Shake a shake
This kind of jitter is mostly irregular jitter
Drops of urine will fly everywhere like scattered flowers.
Could be in the toilet
Outside the toilet
On a shoe
On pants
…….
Although it is difficult to urinate accurately, it is not impossible to solve it.
In the meantime, it is necessary to
Treat the disease when it is time to treat it.
Urology department welcomes you
In the meantime, it is necessary to
Fundamentally control the path of urine.
We can reduce h
My parents gave me the leg length.
But we can artificially reduce
Height difference between oneself and pit
For example
If there are some choices,
Urinal > Toilet > Squatting Pit
But even toilets still have height differences.
So you can–
This is a bit indecent
So the best way is-
Sit down
In fact
It is not uncommon for men to sit and urinate.
Thirty percent of men in Japan pee sitting down.
In the meantime, it is necessary to
I know a lot of boys can’t take it
Sit and pee
If you live alone
It doesn’t matter whether you urinate correctly or not.
But if you live with someone
Still need to take care of other people’s feelings
If you feel that
[Standing to urinate is the last dignity of men]
At least
After urinating, wipe the drops of urine casually.
If the boys who can’t do this
It is suggested to go out and pee in the public toilet…….
