The following exam- ple of Arturo cheap avanafil 50mg amex impotence vacuum pump demonstration, a young man who worries excessively about getting sick from contaminated food buy generic avanafil 100mg online impotence young male, illustrates the cost/benefit analysis. He believes that processing food increases the risk of indus- trial contaminants, rodent droppings, bacteria, or viruses entering into the food supply. His primary-care doctor refers him to a psychologist who helps him develop the cost/benefit analysis shown in Table 16-1 regarding his con- cern about food contamination. Table 16-1 Arturo’s Cost/Benefit Analysis Benefits Costs I don’t eat contaminated food. No one can be safe all the time; I could get hit by lightning or some- thing and die early anyway. Furthermore, he sees that some of his perceived “benefits” for his worry are illusions. Thus, he could eat healthy food, stay slim, and still get sick whether he worries or not. Make lifestyle changes that matter and realize that excessive worries can, by themselves, make you sick. Seek professional help if your health concerns persist in spite of your best efforts. Chapter 16: Staying Healthy 247 Tabulating Risks of the Modern World In the early 1900s, you were lucky to live to age 50. People died of contagious diseases like tuberculosis and influenza or infections caused by simple inju- ries. Heart disease, dementias, and cancers were less likely to be the cause of death only because people succumbed to infections before reaching old age. People over 100 are the fastest-growing sector of the world population, with expectations that this segment will be over 6 million strong by mid-century. Today, heart diseases and cancer have replaced contagious diseases as the most likely cause of death. Yet, it seems that as people live longer, they don’t appear to be living healthier. The skyrocketing costs of healthcare not only reflect improvement in care but also the fact that many more people have chronic diseases. In the following sections, we take a look at when it makes sense to keep tabs on diseases and epidemics and when you can safely ignore them. Examining the evolving realities of diseases and treatments Paradoxically, longer life spans and modern medicine give people more to worry about all the time. Many diseases become more frequent with age, such as cancer, arthritis, dementia, and hormonal disor- ders, so obviously, in an aging population, the risk for getting sick is greater. Second, so-called advances in technology and medicine allow doctors to find disorders they never looked for in the past, such as prostate cancer. Even though the vast majority of “sufferers” have relatively few symptoms and eventually die of other causes, we now worry about such cancer and often experience significant side effects from the treatment itself. Unfortunately, the surgical treatment of osteoarthritis has recently been found to be no better than a placebo — the treatment consisted of giving some patients a sham surgery (the patients thought they received surgery, but actually did not — the surgeons even cut open their knees and stitched them right back up). For example, the dreaded colonoscopy can detect benign polyps before they become cancerous. Yet another interesting cost of medical advancement is the additional risk that some treatments carry. Known to increase the risk of certain cancers, it’s now vigorously treated with medication to reduce or eliminate stomach acid. So people being treated for acid reflux may be at greater risk for food poisoning. Other medications such as antipsychotics (see Chapter 9) can help people with severe mental disorders but lead to weight gain and diabetes. Osteoporosis is defined as significant loss of bone density that results in an increased risk of bone fractures. However, a rare side effect of long-term use of these medi- cations results in collapse of bones (the very problem the treatment is sup- posed to deter). Blood pressure is now considered high and treatable at lower levels than before; the cutoff for normal cholesterol has also dropped. That can be a good idea, but what constitutes dis- eases sometimes gets out of hand, such as when normal sadness is defined as serious depression in need of medication. Consider another example: Minor loss of bone density was once thought to be a common and normal result of aging. But today medical providers have started treating a “new” condition called osteopenia — a milder loss of bone mass than osteoporosis. Treating this newly diagnosed “disease” has led to a huge increase in sales of the drugs originally developed for osteoporosis.
