The PP + singular verb

Thus pets are important in the treatment of depressed or chronically ill patients. In addition, pets are used to great advantage with the institutionalized aged. In such institutions it is difficult for the staff to retain optimism when all the patients are declining in health. Children who visit cannot help but remember what their parents or grandparents once were and be depressed by their incapacities. Animals, however, have no expectations about mental capacity. They do not worship youth. They have no memories about what the aged once was and greet them as if they were children. An old man holding a puppy can relive a childhood moment with complete accuracy. His joy and the animal’s response are the same.
