People who own pets often remark on what good company they are and what fun they have together. Pet experts and researchers identify many other additional benefits that come with pet ownership or interaction. In addition to those mentioned thus far, pets ease stress and anxiety, aid relaxation, provide a sense of security, and are a great diversion from troubles. One medical study showed that people's blood pressure would fall when they stroked their pets. Pets are increasingly being used in therapy for the elderly and those who have Alzheimer's disease or physical disabilities. One lady in Tucson, Arizona, shares her lovely little dog with many elderly nursing home residents. She takes her dog there at least once or twice a week and allows the elderly people to hold and pat her little dog. They eagerly await its arrival and always ask when she and her dog will be back. She is just one of hundreds of people who share their pets with with the old and lonely.
