Lethbridge Herald, The (Newspaper) - November 20, 1974, Lethbridge, Alberta 30-THE LETHBRIDGE November 20, 1974 Ask Andy Andy sends a complete 20 volume of the Merit Students Encyclopedia to Carl Wi'gener, age 11, of Newport News. Va.. for his question: How can they prove that animals art- colorblind? Color vision in humans is hard to detect. For example. suppose you call a certain color red. Perhaps a friend sees this as the color you call green Imagine how hard it is to test the color vision of more than a million animal species. Besides, colorblindness in the animal world is different from most human colorblindness. Scientists who study animal vision usually start by ex- amining the eyes. If certain color sensitive cells are not present, then the animal sees the world in black and white and tones of gray. A very small percentage of people have colorblindness of this kind. But most people who are colorblind merely confuse either the blues and yellows or the reds and greens. Cats, dogs, pigs, horses and cattle are totally colorblind. But most animals have color vision, and some seem to see colors more or less as we do. Testing each species calls for a lot of patient experiments. As a ruie. the tests are based on the animal's food preferences. For example, we can test a bird by setting out several bowls of different colors. We put food in the red one and leave the others empty. After checking the whole setup a few tiroes, he flies straight to the red bowl. He will do this even when the shapes and positions of the colored dishes are changed. After he proves he can recognize red, the food can be switched to test him with other colors. Experiments of this sort show that the daytime birds can detect colors. So can cer- tain reptiles and fishes. One of the favorite fish subjects is the cute little blenny who darts around tidal pools. His big round eyes soon learn to select the color that matches his favorite food. Flowery shapes and colors and also various lights are used to check the colors seen by insects. For example, bees tend to ignore reds and select blues and yellows. They select yellow even when the model is merely a paper flower. Under a red light, the white cabbage butterfly seems to be quite blind. Apparently red is one of the colors she cannot see. On the other hand, under a red light, the tortoise shell butterfly is able to select a red flower. Bees and several other animals seem able to detect subtle colors in shades of gray. The luna moth can detect colors in ultraviolet rays which we cannot do. Dogs have been tested with a checkerboard of light and dark gray box tops. One square is colored, and this one hides a reward. But no dog can distinguish the colored square from the various shades of gray. Dogs and also cats are totally colorblind.

Suddenly, declarer realized his predicament- if he rose with the ace of spades, he would be unable to clear the ace of diamonds from his hand and then re- turn to dummy to cash the jack of diamonds. South had no alternative but to hope that West had led away from the king of spades, so he played low from dummy. Un- fortunately. East produced the king, and that spelled down one. By holding up the ace of hearts until the third round, declarer discovered (hat the suit split 4-3. Thus, he could lose no more than three heart tricks, and couid afford to lose a trick in diamonds. What he could not afford was to squander one of dummv's entries for a needless finesse.

His legs were bothering him so bad he could not walk without pain. The doctors found he had calcium deposits in his arteries and the blood was not getting through. They operated on him and, from what I understand, did a bypass of the clogged arteries with plastic. Anyway, the operation was very successful and he is once again very ac- tive. The doctors also told him he had a slight case of emphysema. He has been told repeatedly he should not smoke (he smoked around three packs a He has cut down considerably, but will not quit. To be frank with you, I don't think he believes the doctors when they say it could cause him more problems. He has a family, and I think he is being very selfish, but since I have never smoked maybe I don't understand what it's all about. Please explain just what could happen. He is 56. Dear Reader He sounds like most smokers. Cutting down helps some, but a person who already has lung changes should quit entirely. The tissues in the lungs affected by cigarette smoking need to be free of exposure entirely so the ceils can start to grow nor- mally again. It will take several years to get the max- imum benefit from stopping smoking anyway. As long as he continues to smoke the damage from heavy smoking will not be adequately reversed. As the lung changes progress they reach a point where it is impossible to reverse the process. These people end up literally dying gasping for breath. H is one of the most unpleasant deaths I know of and rivals or equals ihc problems of widespread cancer You can relieve pain in cancer, but there i? almost nothing the doctors ran do to relieve the breathless, smothering feeling of the person with advanced lung heart and vascular disease. The diseased artery your brother had surgery for is warning enough. The changes began with fatty deposits in the arteries and then calcified. The same thing happens in the heart. Sudden, death from heart attack in smokers is almost three times the rate in non smokers with all other factors being equal. Strokes are also increased in heavy cigarette smokers. Your brother should be thankful he is not already crippled from disease of his arteries and can thank those wonderful advances in medicine that have made it possible for him to have a se- cond chance. A stroke may not give him a second He could be severely disabled but still alive. Yes, he is at the very least not giving enough weight to the seriousness of his problems. It is tough to quit smoking, but not impossible. Men. incidentally are more successful at this than women. He needs to quit, not cut down or use a milder cigarette. No one should smoke, in my opinion, but cer- tainly no one with his medical probiems- Send your questions to Dr. Lamb, in care of this new- spaper, P.O. Box 1551, Radio City Station. New York.
