They found optimism had a huge impact on physical health. The study examined overall longevity, survival from a disease, heart health, and immunity. Cancer outcomes, pregnancy outcomes, and pain tolerance were other health topics studied. It seemed that those who had a more optimistic outlook did better. They also had better results than those who were pessimistic.
