Dr. Robert Waldinger

And when they got to be in their 80s, we asked them, looking back on your life, what are you proudest of?

Nobody mentioned their accomplishments.

Get out of here.

Everybody.

They talked about their relationships with people.

They said, you know, I was a good partner.

I was a good dad.

Why do you think that is?

Who's counting over here?

It's like, I'm so embarrassed that I even know that number, except when it passed 50 million, they got all excited.

Why do you think it's had so many views?

Well, so when I gave it,

I gave it at a little elementary school auditorium in suburban Boston.

It was a TEDx talk.

And I thought people were going to laugh me off the stage because I was talking about something that I thought was so obvious.

And instead, it went viral.

And I think it's because...

People are really concerned about growing social disconnection, how disconnected we are from everybody, how isolated we are.

And I think that my kind of shining a light on it was something that got people's attention in a way that I didn't expect it to.

Well, because I thought it was so obvious.
