Scientists have been studying people who remain healthy into their 90s and beyond 100 years. They found that while genes play a role in longevity, lifestyle has a larger impact. Factors such as maintaining a healthy diet, regular exercise, social activities, and attending religious services are associated with longer life. Additionally, people living in so-called 'Blue Zones'—such as Loma Linda in California, Okinawa in Japan, and Sardinia in Italy—tend to live longer and healthier lives. These populations typically follow a plant-based diet, stay active, and value family and community relationships. Studies also show that higher education levels contribute to maintaining brain health and delaying cognitive decline. While some people naturally live longer due to genetic advantages, most can extend their healthy lifespan through a healthy lifestyle.
