Americans' stress level is down for the first time in almost five years, according to results of  the American Psychological Association's annual survey, Stress in America: Our Health at Risk.

The nation's stress level is 5.2 on a 10 point scale in 2011, down from 6.2 in 2007.  39% of those surveyed say their stress rose last year; 17% say it dropped; and 44% say it stayed the same.

That doesn't mean that our stress has simply gotten easier, its that we are starting to get used to it.  Experts say the decline in the number of people nationwide that are stressed out is because being overhwelmed has become the new normal.

What causes us stress?  Money, work and the economy top the list nationwide.

The APA  survey also found that young adults ages 18-32 are less likely than older adults to feel stressed by the economy, 54% of them are stressed compared to 71% of baby boomers.

Other stress factors?  Family responsibilities, health concerns, job stability, housing costs and personal safety.
