The linked article from Northwestern Medicine discusses four habits that contribute to the health and wellbeing of those with very long lifespans. These habits include engaging in regular physical exercise, maintaining a healthy diet, getting enough quality sleep, and staying mentally active through lifelong learning and cognitive challenges. The article emphasizes the importance of aerobic exercise in particular, as it has been linked to improved brain health and reduced risk of cognitive decline. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins is recommended to support brain function and overall health. Sufficient sleep is crucial for cognitive function and memory consolidation. Finally, staying mentally active through activities like reading, puzzles, and social engagement helps to keep the mind sharp and may contribute to longevity and a high quality of life.
