> [!tldr] **Good relationships with others make life worth living and keep a brain youthful.** The key to a long, happy, and healthy life lay with the quality of your relationships you have. The people you know you can truly rely on to go to when the going gets tough. The people you turn to at those times. People who have good, close relationships with others are much less likely to develop dementia than those who are alone. The famous Harvard study on wellness found that the single best predictor of longevity was not diet, sleep, or exercise - but instead **our relationships**. Not only does regular and on-going *in-person* quality time with family and *especially* friends protect us from (or at least slow) mental decline, but it's also associated with a reduction in all-cause mortality. **** # More ## Source - [[Keep Sharp]] - [[Eat Your Ice Cream]] ## Related - [[Alzheimer’s ≠ Dementia]]
