It's a place for humans to move around to.

Adopting that policy is the first and the biggest.

And then once you adopt that policy, we can bring in experts that help the city planner plan for walkability.

And by the way, that saves money over time.

We all think we want to drive places fast, but when you close your eyes and you imagine a street with cars whizzing by at 50, 60 miles an hour and the smell of their exhaust,

and the stress that it generates and the danger for us and our children, we actually don't want to live in a place like that.

If you close your eyes a second time and you think of a walkable city where cars ease by at 30 miles an hour, there are people gathering on sidewalk cafes, there are trees overhead,

It's safe for our children to play.

It's easier to stop into businesses because you're not whipping by at 50, 60 miles an hour.

That's the place you really want to live.

And once you help people understand that, it's pretty easy to get policy to follow.

So I would say that's a really big one at the population level.

I'm of the belief that most of us are on what I call a seafood diet, which is to say that we eat the food we see.

Cornell's food lab has shown that if you have a bag of chips on your counter with a clip on it, you're going to eat a lot more of that junk food than if it's out of the way, a junk food drawer, a place you have to stoop down or reach up high or around the corner in the pantry.

We're all going to bring junk food into our houses, but one of the easy strategies is to make sure they're hidden so we don't see those foods every time we walk through our kitchen.

Conversely, having a

Fruit bowl at the most prominent spot in our kitchen and keeping that fruit bowl full, one of the greatest nudges to get more fruit into our diet.

Secondly, you hear a lot more about sleep lately.

I'll tell you what, having blackout curtains, invest in blackout curtains that are easy to put up and down.

Great investment.
