So here's my advice to city planners. Make your city runnable. Runners are the first wave of troops bringing human activity back to the urban core of any city. Where we go, others will follow. The connection between runnability and livability is so clear (at least to me), that it's surprising that new developments consistently leave pathways out of the plans.

Prior to the 1976 Olympics, I was a 5,000m runner.

Grizzly bears eat people without the benefit of music.

Avoid any diet that discourages the use of hot fudge.

Without ice cream there would be darkness and chaos.

Coaches know that a parent publicly scolding his kid after a race will not help the athlete perform better.

A good teammate is someone willing to get outside of personal thoughts and emotions, a friend who tries to understand, appreciate, and encourage other members of the team.
