How Long Have Social Networks Impacted Our Health?

One other things that Nicholson and I talked about and are both connected is the telephone, and it's really interesting to go back to the initial adoption of telephone, yet all of the same issues that we came up with, people who worry about their privacy, with people talking about how this is going to completely change society.

We're going to be a totally different people, and what we discovered over decades was that it was a useful tool but fundamentally we were still the same human beings we always were. And so one of the things I always tell people is that we still have the same brains we had before this one.

But we have the same brains we had at 100,000 years ago more or less. And so one of the things that we've done is we've tried to push back further and further in time a comparison between the way we are now, and the way we used to be. [xx] study on this group of hunter gatherers in northern Tanzania called The Hadza.

I mean we actually had photographic sensors of about 1000 of the people in this group, and we showed these pictures to them, and we asked them to tell us who are your friends so that we could map the social networks, and their show social networks than be compared to modernise such networks from all around the world.

And guess what we found. We found we're almost exactly alike. We are making friends now in modernized society same way the hunter gatherers who probably lived away all of our ancestors who said a 100,000 years ago, make friends, the same kinds of patterns are recurrent over the last 100, 000 years.

So, this is not new. This is a fundamental part of what it means to be human, and this is one of the reasons why I think that technology has taken up this is growing like a wildfire, because for the first happening, there's much going on online, there's tapping into this deep fundamental desire to connect.
