Those who do it also do these things, according to The Canyon Ranch: Guide to Living Younger Longer:
Work hard throughout your life and never functionally retire
Exercise for fun and pleasure — keep playing
Make and maintain social connections
Stay curious, explore, learn — and keep laughing
Cherish and preserve your independence
Find meaning and purpose in living
Believe in something bigger and better than yourself
