“This is an important concept, the concept of protection. Life is hard, and sometimes it comes at you in full attack mode. Warm, connected relationships protect against the slings and arrows of life and of getting old.
“Once we had followed the people in the Harvard Study all the way into their 80s, we wanted to look back at them at midlife to see if we could predict who was going to grow into a happy, healthy octogenarian and who wasn’t. So we gathered together everything we knew about them at age 50 and found that it wasn’t their middle-aged cholesterol levels that predicted how they were going to grow old; it was how satisfied they were in their relationships. The people who were the most satisfied in their relationships at age 50 were the healthiest (mentally and physically) at age 80.”
