According to the theory of evolution, human beings evolved from animals. The picture below compares a human being to an animal.

One of the most obvious differences between the human being in the picture above and the animal, is that the animal is standing on four legs, while the human is standing on two legs. But human beings are evolved from animals, which means a human being is an animal. So a human being should really be on all fours as shown in the picture below.

The human being in the picture above looks like an animal. All four limbs are planted on the ground.

If the human being in the picture above wants to masturbate, he must pick one of his arms up off of the ground, and reach back between his legs to get to the genitals, as shown in the next picture.

The right arm is reaching back between the legs for the genitals. The hand is sticking out behind the legs to make it clearly visible.

An animal that is standing on four legs is balanced on four legs. The animal does not fall down, because the four legs form the four corners of a rectangle, and a rectangle is a naturally stable structure.

But the human being with has right hand reaching for his genitals, only has three legs on the ground. One of the corners of the rectangle is missing.

The animal in the picture above is not balanced. It should have a leg at each of the four corners of a rectangle, but the animal above only has three legs on three poins of the rectangle. That means the animal above is not balanced.

What happens to something that is not balanced? Whatever it is will start to fall down as demonstrated in the picture below.

The upper body has twisted down towards the forward right corner of the rectangle. There is no arm to hold up the forward right corner of the body, so the body starts to fall down towards that corner.

When the body falls, the arm on the opposite side will go up into the air in reaction to the other side of the body falling down.

The picture below shows what happens after the body falls all the way to the ground.

Because there is no arm to hold up the forward right corner of the body, the entire body falls onto the right shoulder and the right side of the head. As the body falls, the right shoulder rotates downwards and the left shoulder rotates upwards. The body continues falling until it ends up completely on the ground, with the face in the dirt.

To reiterate:

This series of pictures shows why masturbation makes a human being blind and crippled. A human being is a four legged animal that can walk on two legs if it wants to. But a human being was designed to walk on four legs.

When the four legged human being reaches for his genitals to masturbate, he is no longer balanced on the four corners of a rectangle. His body is now crippled because instead of walking on four legs like he is supposed to, he is only walking on three legs.

Because the body is crippled and unbalanced with only three legs supporting it, the body will fall down towards the corner of the body corresponding to the hand reaching to the genitals for masturbation. The body will fall down until the shoulder ans the side of the head corresponding to the hand used for masturbation, hit the ground.

The side of the head in the picture above looks like it has been driven down into the ground? That picture provides the intuitive reason for why masturbation makes a human being blind. The eye on the side of the head smashed flat into the ground cannot possibly see anything. The eye is smashed into the dirt, so all it could see would be dirt.

That whole side of the head that is smashed into the ground in the picture above will be changed. There will be brain changes, sinus changes, the already stated vision changes, and visible changes to the physical structure of the face.

The next picture shows the body with the face smashed into the dirt from the other side.

In the picture above, that human being only has one eye. Only one of his eyes is visible.

The other eye is in the dirt, so even if the eye worked fine, all it could see would be dirt.

The masturbation caused tilting and twisting of the human body when it is on all fours, still occurs when a human being stands erect on two feet. Masturbation will still pull the body towards the masturbating hand, and the body will still rotate towards the masturbating hand, even though the human being is standing up on two legs.

Any person can confirm this for themselves by either viewing pornography of people who are masturbating, or they can look in the mirror and watch themselves when they masturbate. If they are serious about the act like they are really working at enjoying what they are doing, their body will bend and rotate, and they can see it in the mirror.

This picture below compares the computer model to a man who is supposed to be masturbating

The real person looks similar to the computer model. They are not exactly alike because the computer model is using it's right hand to reach for the genitals, while the real man is reaching for his genitals with his left hand. If you reverse either the computer model, or the man, then the computer model and the man will look similar.

The computer model and the man are both bent over. The shoulder of the masturbating hand is tilted downwards on both the real man and the computer model. The angle of the camera on the real man is not very good, by the man's head is slightly rotating and tilting like the head of the computer model is rotating and tilting.

The shoulder opposite the masturbating hand is high up on both the computer model and the real person. The opposite arm of the computer model was raised into the air to emphasize the rotation of the torso. The real man's opposite arm is being used to hold himself up. The opposite arm of the man and the computer model are really similar.

In the picture above, the masturbating hand of the computer model and the man are reaching down for the genitals, while the other hand is bracing the upper body so it does not fall down.

The entire sequence of the man faking masturbating can be seen here. There are no graphic sexual visuals in the video.

If you watch the video sequence, you will see that the man's body moves towards the masturbating hand. Over a period of years of masturbation, the body will start to stay in that tilted over and rotated position. That is what causes a human being to be crippled and blind from masturbation. The continual pulling on the body by the masturbating hand.

The exact details of how the continual pulling on the body changes the body, are much to complex for this simple explanation. Anyone wanting details, will have to go to the other sections of the site with more detailed information.
