A super drug that could remove Alzheimer's(痴呆症) ，heart disease and diabetes(糖屎病) and help people live to 100 is being developed by scientists. Their research is based on the iden?tification of three genes that improve long and healthy lives and prevent diseases of aging. Medi?cally controlling the proteins made by the " longevity genes" will allow millions to live longer, predicts Nir Barzilai.

Those people whose DNA strongly features the three genes are 80 percent less likely to de?velop Alzheimer's. The genes also fight against the deadly impact of smoking, bad diet,obesity and lack of exercise.

Already，several laboratories are working on a pill to imitate the benefits of the genes and Dr Barzilai thinks it could be tested within three years. The pill could remove some diseases that damage the old people. "The advantage of finding a gene that involves longevity is that we can develop a drug that will imitate exactly what this gene is doing," he said. "The biology we're trying to uncover is that if we can imitate that,long life can be really terrific."

Of the three longevity genes, two increase the production of so-called good cholesterol(胆固醇) ，which reduces the risk of heart disease. The third prevents diabetes. They were discov?ered by Dr Barzilai's team while studying the DNA of 500 Ashkenazi Jews with an average age of 100. The chances of living that long are one in 10,000 but the study group―which shared relatively few common ancestors―was 20 times more likely to hit the century. Dr Barzilai said, "Thirty percent of them were overweight and 30 percent smoked two packs of cigarettes a day for more than 40 years,however they could still live to 100."

But Andrew Ketteringham, of the Alzheimer's Society, said. " Alzheimer's disease, a most common disease, is likely to be caused by a combination of genetic disposition(遗传倾向) ，lifes?tyle and life events. Many genes are probably involved.”

( ) 2. Why does the discovery of the longevity genes mean a lot?

B.the study group is all from the same family

C.good habits have no effects on the health of people
