Floating around in space isn't as relaxing as it might sound. Astronauts expend a lot of energy and endure extreme stresses on their bodies. Their dietary requirements are therefore different from those of their gravity-bound counterparts on Earth. For example, they need extra calcium to compensate for bone loss. (Bones tend to regenerate slower in space, and the loss of mass begins almost immediately after takeoff). A low-sodium diet helps slow the process, but according to Kloeris, that's easier said than done. "There are no refrigerators in space, and salt is often used to help preserve...
...That may sound like a cop-out. At least until you consider how many other economic forecasters got it wrong.

The economy proceeded to shrink at a pace of 5.5%. (See what to expect when the recession ends...

"In humans, our vocal tract has been hijacked by our language skills," so instead of barking out a random sound, "we articulate our yelp with a word colored with negative emotion...
...against leaders who aren't necessarily U.S allies. Likewise, Chávez needs to realize that his calls for Micheletti's regime to respect the democratic process in Honduras have thrown a brighter spotlight on the democratic process in Venezuela - and that Clinton's remarks, however "disrespectful," might be sound advice for any government...
