Three unique programs that help seniors live independent and healthy lives in very different ways.  We start with the PALS program that trains senior volunteers to help other seniors with everyday living needs, such as grocery shopping, household chores, etc.; then a McKeesport based non-profit that is using Smart Technology to help seniors improve their quality of life; and how pet therapy is being used in nursing homes and palliative care units to not only provide companionship but to help contribute to a longer, healthier life.
