| | Sunlight - advantages and precautions |
 | | Sunlight coming to earth represents only about one part in 2 billion of the total amount of energy radiating from the sun, and yet this is sufficient to supply our planet with about 4.69-million horsepower per square mile. |
 | | Sunlight consists of several types of energy, including cosmic, gamma, and x-rays, ultraviolet and infrared light, and visible light of many colors. |
 | | Regular, controlled, moderate exposure to sunlight, instead of damaging the skin and aging it, actually protects the skin by building up a natural resistance to the harmful effects of ultraviolet light, while giving it a nice velvety texture. |
