For all the new age gurus, yoga studios, juice bars, and metaphysical colon cleanses that exist on every corner of Los Angeles, all that deep breathing and heavy intestine petting isn't doing shit: Los Angeles is the most stressful city in the United States. Apparently, all the good vibrations and power hikes through Runyon Canyon can't make up for the bad air, horrible traffic, crappy economy, and outrageous rent prices. An American Psychological Association study shows that Angelenos aren't just unhappy about their money situation; even when they have jobs, they are totally unsatisfied and all their hard work is taking a toll on their physical health. Driving back and forth from their horrible jobs only exacerbates the problem. The plus side of Los Angeles? The kind of amazing weather that homeless people can really thrive in all year round.
