STOP! You cannot! You cannot leave this show! Do you not understand what you are doing?! You are the first non-stereotypical role in television! Of intelligence, and of a woman and a woman of color?! That you are playing a role that is not about your color! That this role could be played by anyone? This is not a black role. This is not a female role! A blue eyed blond or a pointed ear green person could take this role!” And I am looking at him and looking at him and buzzing, and he said, “Nichelle, for the first time, not only our little children and people can look on and see themselves, but people who don’t look like us, people who don’t look like us, from all over the world, for the first time, the first time on television, they can see us, as we should be! As intelligent, brilliant, people! People in roles other than slick tap dancers, and maids, which are all wonderful in their own ways, but for the first time we have a woman, a WOMAN, who represents us and not in menial jobs, and you PROVE it, this man [Gene Rodenberry] proves and establishes a precedent that validates what we are marching for because three hundred years from today there we are, and there you are, in all our glory and all your glory! And you CANNOT leave!

The caveman lifestyle, in Mr. Durant’s interpretation, involves eating large quantities of meat and then fasting between meals to approximate the lean times that his distant ancestors faced between hunts. Vegetables and fruit are fine, but he avoids foods like bread that were unavailable before the invention of agriculture. Mr. Durant believes the human body evolved for a hunter-gatherer lifestyle, and his goal is to wean himself off what he sees as many millenniums of bad habits.

These urban cavemen also choose exercise routines focused on sprinting and jumping, to replicate how a prehistoric person might have fled from a mastodon.

But the surprising consensus of the paleos is that the city is a paradise.

“New York is the only city in America where you can walk,” said Nassim Taleb, an investor who gained a measure of celebrity for his theories, described in “The Black Swan,” that extreme events can roil financial markets. “People treat walking like exercise,” he said, “but walking is how humans become humans.”

Mr. Taleb, who rejects the label “caveman” in favor of “paleo,” avoids offices (including his own) as much as he can. He prefers to think on the go. Dressed in a tweed coat and Italian loafers, this paleo man is a flâneur, sometimes walking miles a day, ranging from SoHo to 86th Street.

The true test of walkability I think is this: Can you spend a pleasant half hour walking or on transit and end up at a variety of great places? The quality of having a feast of options available when you walk out your front door is what I’m starting to think of as “deep walkability.”

…

In most cities, serious walkers (and bikers) share stories about the routes they’ve taken, hidden paths through the fractured landscape that let you walk safely and happily from one people-centered place to another. A killer urban ap would be one that revealed these urban songlines. A smart urban policy would be one that aimed to weave new walking routes through the whole urban fabric, until places walkers feared to tread were the exception rather than the expectation.

We spent the 00s tolerating the dumbest and meanest amongst us. Let’s spend the Teens promoting the smartest and nicest.

The decade’s battle-lines weren’t drawn between authenticity and gloss or “indie” and “pop”. The fight was between those whose histories were played out in public against others who emerged fully formed, accepting no questions, offering no explanations. This line in the sand pitted Kylie against the X Factor, Gorillaz against Blur, The Horrors against themselves and Lady Gaga against the world. It was magnificent.
