Many factors influence how we age and whether longer lives are experienced in good or poor health. Scientists believe that genetic factors explain only 15 to 30 percent of longevity, while lifestyle factors play a more significant role in why some of us live longer. Optimal sleep can slow biological aging and decrease the risk of dementia. Proper nutrition and when we eat can help prevent the development of disease and boost longevity. Even laughter has a role to play by triggering healthy physical changes, strengthening our immune system, and diminishing pain. This session will explore the science of laughter and its link to longevity, discuss the latest lifestyle behaviors to protect our brains, and give us ways to joke, sleep, and eat our way to better health.
