About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green － a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.

l like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Surely, there are times when we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend.
No two people are the same. Sometimes friends don't get along well, which doesn't mean that they no longer like each other. Most of the time they will go on being friends. Sometimes friends move away, then we feel very sad. We miss them much, but we can call them and write to them. Maybe we would never see them again, and we can make new friends. It is surprising to find out how much we like new people when we get to know them. Families sometimes name their children after a close friend. Many places are named after men and women, if they are friendly to people in a town. So are some schools. We think of these people when we go to these places.
There's more good news for people, if they have friends. These people live longer than those people if those don't have friends. Why? It could be that they are happier. Being happy helps you stay well. Or it could be just knowing that someone cares, if someone cares about you, you take better care of yourself.
