Argument: 题库68. A recent study reported that pet owners have longer,healthier lives on average than do people who own no pets. Specifically, dog owners tend to have a lower incidence ofheart disease. In light of these findings, Sherwood Hospital should form apartnership with Sherwood Animal Shelter to institute an adopt-a-dog program.The program would encourage dog ownership for patients recovering from heart disease, which should reduce these patients'chance of experiencing continuing heart problems and also reduce their need forongoing treatment. As a further benefit, the publicity about the program wouldencourage more people to adopt pets from the shelter. And that will reduce theincidence of heart disease in the general population.
