In Robert Waldinger’s “What Makes a Good Life” he explains the longest study of history and how it went on for 75 years, it was a study on happiness. They studied around 700 men from Harvard and followed them through life to see what factors made them happy. Waldinger observed that some were thriving and some were going in the opposite direction. The researchers took three big things away from the study one being that loneliness kills and that connections are good for us. The second lesson Waldinger explained was that it doesn’t matter how many connections you have it’s the quality of the relationships that matter. The last lesson they found was that a happy relationship can protect your brain, not just your body. Overall Waldinger emphasized that being in good, quality relationships can be beneficial to your health.
