Lethbridge Herald, The (Newspaper) - June 10, 1974, Lethbridge, Alberta 18- THE LETHBRIDOE HERALD Monday, 10, 1974 Ask Andy Lawrence Lamb M.D. CARBON DATING Andy sends a complete 20- volume set of the Merit Students Encyclopedia to Vincent P George, age 15, of San Diego, California, for his question How does carbon dating work9 If you spend exactly one dollar each day, when you are 365 dollars poorer you are one year older Obviously there are simpler ways to figure your age But the months cannot tell the age of a log and the calendar cannot date an old bone For these tasks we need a modified form of the dollar-a-day method In one method, we substitute >ears for a day and the steadily spendable dollars are isotope atoms of carbon 14 Carbon 14 is called radiocarbon because its isotope atoms are radioactive Ordinary carbon has an atomic weight of about 12 Carbon 14 is like ordinary carbon except it's heavier and loses its extra weight by radioactivity Because it breaks down at a steady, dependable rate, it can be used to date logs and old bones Ordinary carbon is present in every living cell Some of its atoms are heavier isotopes of carbon 14 Scientists assume that in all forms of carbon, one atom in a trillion happens to be one of radioactive carbon 14 These isotopes are everywhere Plants and animals consume them with air and food, along with ordinary carbon Meantime, the consumed radiocarbon breaks down at a steady rate while more is added from cosmic rays smashing portions of nitrogen atoms Then no more is added, though the radiocarbon quota in the tissues continues to break down and disappear All radioactive decay proceeds in predictable stages at a steady predictable rate During years, precisely half of the atoms in a sample -of radiocarbon break down and disappear This period is the half life of carbon 14 After years, only one quarter of the original sample is left After years, only one thousandth part of the original quota remains Suppose archeologists find bones and building timbers in a prehistoric campsite They test to find the carbon 14 radiocrabon atom per two trillion ondmary carbons Half the original radiocarbon has had time to decay which means that the bones and trees stopped living about years ago After years, there is one part radiocarbon per trillion parts of ordinary carbon Such a tiny quota is too hard to detect precisely which is why carbon 14 cannot be used to date the remote past Nor can it be used to date minerals or other inorganic substances It is limited to fossil remains of once living plants and animals And the tmy traces of decreasing radiocarbon make it difficult to date fossils much older than a few thousand years What's more, some scientists complain that variations in cosmic rays and other factors tend to upset the carbon 14 system of dating At best, it gives only the approximate age of this old log or that old bone Questions asked by chil- dren of Herald readers should be mailed to Ask Andy, P.O. Box. 765, Huntington Beach, California 92048. (Copyright Chronicle Publishing Co. 1973) Dear Dr. Lamb Please give me some information on the intestinal bypass operation that is supposed to get you down to your ideal weight I am 37 and weigh 310 pounds I have been heavy all my life Diets don't work I have been having trouble with my blood pressure and a recent glucose tolerance test was a little high Am I a candidate for a bypass operation9 Dear Reader The operation that you refer to makes a new opening in the small intestine a short distance from the stomach and connects this opening to the large intestine (colon) In this way many many feet of the small intestine are bypassed Food can be shunted directly through a short distance of the small intestine to the large intestine All of the important food absorption occurs from the small intestine, and, incidentally most of that occurs in the very first part of it The purpose of the bypass operation is to prevent you from absorbing as much of your food as you ordinarily would The undigested food then is dumped into the colon No absorption of food or digestion occurs here So, much of the food you eat then is passed through the system without ever being absorbed and used for nutrition It s true that you can lose a lot of weight with one of these types of operations Recent studies have shown, however, that it can lead to some relatively severe changes. It can affect the liver and cause permanent liver damage It's often not so easy to return to a normal digestive process by attempting to put things back the way they were, either In general there have been enough complications following this type of procedure that I personally cannot recommend it to anyone The last thing you need is a permanently damaged liver What you do need is a regulat consistent program that puts you on a good, balanced diet furnish- ing all the nutritional elements you need You must learn enough about nutrition to understand what this is Then you must follow such a program every day, not as just a short-term diet program and then return to your previous habits You may need to reorganize your life style in a way to avoid food and certain habit patterns that trigger eating Manv people have conditioned responses which cause them to eat when they really don't need the calories at all It's true that being overweight can contribute to problems of high blood pressure and diabetes It is important that you get on a good program and stay with it But, I think you ought to forget about the bypass operation A person with a weight problem as severe as yours really needs a three pronged approach to the problem A good healthy diet needs to become part of your life You should have some type of suitable exercise program, even if that is just walking to start with And because you have so much trouble staying on a diet you probably need some psychiatric help A person's motivations for eating are a big factor in the habit of overeating You could use the support It is worth it because you are already having medical problems that cannot be properly treated without controlling your weight problem Send your questions to Dr. Lamb, in care of tbis newspaper, P.O. Box 1551, Radio City Station, New York, N.Y. 10019. For a copy of Dr. Lamb's booklet on losing weight, send 50 cents to the same address and ask for "Losing Weight" booklet.
