Obvious and important: observations in the article "4 things the world’s longest-living people—residents of ‘Blue Zones’ like Okinawa and Sardinia—do to stay healthy and happy" by Renée Onque (CNBC, 2023-09-16), citing Dan Buettner:

• Exercise — "They move naturally." — walking, gardening, and other frequent, low-intensity physical activities
• Optimism — "They have a positive outlook on life." — often via faith, purpose, or a "true calling"
• Diet — "They eat wisely." — in moderate amounts, of mostly plant-based foods
• Relationships — "They value connection." — with family, friends, community

... not a lot of rocket science, and not bad ideas to practice!
