Hey, Ned.

Thanks for being here.

Nice to be with you.

So what is loneliness?

How do you define it?

How do you look at it?

I love that definition that you're feeling what isn't there, because as soon as you said that, I could feel it.

I mean, that's exactly what it is.

It's that absence of something that you want or need or miss or something.

So help me understand why, what it is about loneliness that makes it so dangerous.

Is it the loneliness itself, or when you are lonely you tend to do bad things like drink more, smoke more, eat more, or is there something inherent about loneliness that is harmful?

Yeah, and anybody who's ever had a dog knows that that relationship is very fulfilling.

But it's still a human-dog relationship.

It isn't the same as connecting with people.

But what is the reason, do you think, that people have such trouble connecting with people?

Because, you know, there's a lot of people.

There's like billions of them.

So you would think that connecting with people would be easier than it apparently is.

Why do some people find themselves lonely?
