What is the minimum amount of light that a human being requires to live? The lighting books fill us with standards and specifications to follow. Minimum of light in restaurants, rooms, writers, bathrooms, even toilets and toilets. Like there are minimums in the streets, be pedestrian cars bicycles, high and low traffic. Per which is the minimum amount of light that the human being requires to live. All this is speculative or relative in each person. For example, I like the rays of light in the morning, those that are marked by the interruptions of the shadows created by other objects, buildings or plants. I like the diffused light of rainy clouds and clouds that are foggy that paint an entire atmosphere of a color, gray, white, orange sea. I like those sunsets of powerful intensities reflected in the materials that the light perches. Those orange edges in the edges of the windows or when the trees appear to be red. It even fascinates the darkness of the night, the one that tells my body, resting or changing activity. I like the darkness of the stars that generate thoughts of parallel worlds. The darkness that helps my eyes penetrate my mind and body into the world of dreams. I like the darkness of the moon that paints the fields of a silver color. And I like the dark, of that deep blue, before the sun rises, that dark that betrays the entrance of the day. But if someone told me which of these amounts I would stay, at the very least, it would be difficult for me to choose. I would be afraid of what it can cause me, tired of sight for not seeing well, sadness or depression or tired of not being able to enter the world of my dreams or a simple rest.
