So I'm going to solve this integral for you intuitively, and I think it'll make some sense.

If you're under 50 we want you to work four more years.

Tough, yet rational and ethical.

Obviously your rent doesn't increase every month, but I assume it does fairly continuously.

Either way.

It has to be. It's the only possible explanation.

You could do it that way.

So in this case maybe at least five or six years.

You might say, eh, that's not really irrational.

Tra la! What ho!

There are as many different ways of being rational as there are human beings on the planet, and that's one of the glories of human existence.

And in this particular case we were just interested in the replicability of that.

In this question I would like you to check all the boxes that are true.

Well, you're acting that way.

This is reasonable.

The whole business it's unreasonable from beginning to end. Quite reasonable, said the Invisible Man.

I could see her struggling with the thing.

The same is true over here.

That although it looks really reasonable, let's say I make this 3 annual appreciation assumption.

At the bottom of what we can know for sure are things that are physically obvious.

There must be a rational explanation for this.

It doesn't deal very well with irrational opponents.

If I follow the model, then tallness is also contagious.

Now there's one alternate way that you could factor this and it'd be completely legitimate.

So Bill must be tall.

The fact is it's that uncertain part that should move us towards this.

Any reasonable explanations?

Can I still put any x value in here and get a reasonable answer?

We first capture the physics with a mathematical model of how the machines behave.

And in both macro and micro economics, there is especially in the modern sense of it, there is an attempt to make them rigorous, to make them mathematical.

So this notion of loss aversion kicks in when it comes to savings too, because people, mentally and emotionally and intuitively frame savings as a loss because I have to cut my spending.

So these are dollar bills right here being printed, either physically or electronically.

But it's also clear that prosperity goes beyond this.

Now one more question for this same game tree.

And I found there were planning techniques that I could take and adapt to our biological need, and from those I developed what we call holistic management and planned grazing, a planning process, and that does address all of nature's complexity and our social, environmental, economic complexity.

So you say, Sal, what happens if I have the money in six months?

We're reasonable people.

People do get HlV because they do stupid things, but most of them are doing stupid things for perfectly rational reasons.

What's interesting is that something like 30 to 50 percent of the brain is devoted to visual processing.

Mother Theresa, she was rational.

It's gotta be sort of a relief, right?

So maybe we'll cancel some debt and all of that.

And Alice and Bob both understand what's going on.

If I'm going to get an 8 return on my money, that's my benefit, it makes sense for me to borrow it at 5 .

One being physically separate, but with a collective consciousness.
