🤝 The Power of Relationships
Strong social bonds—family, friendships, and community—act as a buffer against cognitive decline and depression. Loneliness, by contrast, is as harmful to health as smoking or obesity.

🧩 Curiosity and Cognitive Flexibility
A key predictor of successful aging is openness to experience. Learning new skills, staying curious, and trying unfamiliar activities preserve mental agility and reduce the risk of cognitive decline.
