Actions that you take in your early adulthood and middle age will result in a vibrant old age, according to Dan Buettner (endurance athlete, speaker and author). Here are tips from his latest book, Blue Zone Solution:

• Be social. Hang out with people who support healthy behaviors

• Find an activity, passion or career that motivates you and gives your life meaning

• Engage in regular physical activity such as with a walking group, gardening or doing errands by foot or bicycle

• Eat a mainly plant-based diet
