Will crime cripple Rio's Olympic ambitions?
Navigating the morning rush hour on a skateboard is ambitious. Doing it with a surf board under your arm may just be suicidal. By juggling the Pope, Carnival, the World Cup and the Olympics all in the space of just three years, Rio de Janeiro is perhaps similarly crazy.
But, to stretch the analogy just a little too far, my skateboarding surfer carried off his challenging commute to the beach with a lot of style and, as far I could see, only the odd wobble. So, can Rio pull off the same trick?
The mayor of what locals like to call "the marvellous city" certainly thinks so. Eduardo Paes took me on a tour of Rio de Janeiro by helicopter.
There's no better way to see the Olympic future than from the air. We flew over the site of the Olympic village.
While the buildings certainly aren't finished yet, preparations, he says, are on schedule.
State of the Union: Obama tinkers around the edges
Tonight, President Barack Obama promised a "year of action".
But if this speech is any guide, it should more accurately be called a "year of quite small, tinkering around the edges, do what I can it in a very difficult environment, and, oh and by the way, my time is running out, actions".
State of the Union: Obama promises action on inequality
Gone is the audacity of hope. This State of the Union address didn't promise big changes on anything - there was no transformation on offer here.
But this address had the virtue at least of touching on bread-and-butter issues that genuinely affect millions of Americans - savings plans for workers who don't have them, health insurance, training schemes and the minimum wage, just to name a few. For poorer Americans improvements in any of those would make a huge difference.

As Barack Obama prepares to give his annual address to the US , the BBC's Katty Kay looks at obstacles in the way of his agenda
Washington can be a cold, cruel city, as anyone who is living here this freezing January is well aware. And as he heads into his sixth State of the Union address, no-one is feeling the chill more than Barack Obama.
100 Women: How US mothers are the new breadwinners
Seventy years ago Rosie the Riveter bared her impressive biceps and summoned American women into the workforce. Called to duty in the service of a country at war, women responded in the millions.
In the decades that followed, women's professional fortunes rose. Today they are chief executives and senators, doctors and lawyers, astronauts and engineers. They are also earners.
Military rape: Saxby Chambliss, hormones and problems at the top
The Senate armed services committee is holding hearings on military sexual assault. But the BBC's Katty Kay wonders if the attitudes of those tasked with addressing the problem are actually making it worse.
Gee whiz, there's a hook-up culture in the US military, where hormones are running rampant and before you know it, these things happen. Sew together the comments of a couple of elderly white men in positions of power (the US Senate and the Pentagon) and that's the grossly misleading picture that emerges of sexual assault in the American armed forces.

Christine Lagarde's mission to save the global economy
Over the past month the BBC has had rare access to International Monetary Fund boss Christine Lagarde. Now, as European leaders meet in Brussels, she will be at the centre of the fight to avert another financial crisis.

Josh Romney: 'My father is the ideal candidate'
Voters in the rural state of Iowa are preparing for the first test of the US election season as they choose a Republican candidate to take on Barack Obama for the White House in November.
Mitt Romney's son, Josh, explained why his father's experience makes him the ideal candidate.
