In the days before elevators, there was no such thing as a penthouse on the top floor. The highest floors of a building had cheaper rents because the stairs were hard to climb.
Caracas, Venezuela, is organized roughly the same way, with many poor neighborhoods climbing up the sides of a mountain valley. Some of the poorest homes are among the most remote, accessible not by any road but by alleyways and long flights of stairs.
Tonight, in Flint, Michigan, a limousine is going to pull up to a nursing home and take a 79-year-old patient for a long-awaited night out on the town. Seven years ago, Evie Branan suffered a stroke that left her in a semi-coma. In May of 2011, she tumbled out of her bed, bumped her head and woke up, and her very first words were a request.
EVIE BRANAN: I said I wanted to go to a Bob Seger concert.
Now to Paris, France - where a walkout briefly shut down one of the world's most visited museums. Our last word in business: Pickpocket Protest.

As Venezuela's president, Hugo Chavez thought in grandiose terms, and his country's vast oil riches enabled him to act on his vision. But Chavez died before he had to deal with the flaws in his model, and some hard choices await his successor.
Key to Chavez's notion of "21st Century Socialism" was the redistribution of Venezuela's oil earnings. The country's oil reserves — estimated by the Organization of Petroleum Exporting Countries to be the largest in the world — are worth tens of billions of dollars a year in potential revenue.
Researchers in California described Wednesday their new method for mass-producing the key ingredient for the herbal drug artemisinin, the most powerful antimalarial on the market. Already, the French drugmaker Sanofi is ramping up production at a plant in Italy to manufacture the ingredient and the drug.
Global health advocates say they expect this new method of producing artemisinin will at last provide a stable supply of the drug and cut the overall cost of malaria treatment.
Scientists reported Wednesday that they had developed a way to measure how much pain people are experiencing by scanning their brains.
The researchers hope the technique will help doctors treat pain better, but the work is also raising concerns about whether the technique might interfere with doctors simply listening to their patients.
Now, when someone is in pain, a doctor has no way to judge its severity except to ask questions, a method that often is inadequate.
