“I argue that the most powerful thing you can do to add healthy years is to curate your immediate social network,” said Mr. Buettner, who advises people to focus on three to five real-world friends rather than distant Facebook friends. “In general you want friends with whom you can have a meaningful conversation,” he said. “You can call them on a bad day and they will care. Your group of friends are better than any drug or anti-aging supplement, and will do more for you than just about anything.”
In my early thirties, I noticed my circle of friends getting smaller as many of friends, and myself, started settling down. Then in my late thirties, as everyone was starting families, the number of friends got even smaller. This is definitely a feature not a bug. I wish I’d learned this sooner. Letting go of negative friends is hard, but benefits you in the long run. The small circle of friends I have definitely fit this description.
