Lynn: It's no surprise that the homeless have a higher incidence of premature death.  Chronic alcoholism cuts down on your lifespan.  Drug addiction cuts down on your lifespan.  Smoking cuts down on your lifespan.  The lifestyle of the seriously mentally ill often contributes to an earlier death.  Virtually every precursing element leading to homelessness also shortens one's lifespan.  Obviously, many community organizations work very hard to help individuals address all these issues.  Yet, we know there are still thousands of individuals in need of help.  

Your comment "leaving people without shelter kills them."  is a very simplistic, accusatory and conterproductive assessment.  We are not your "enemy" or the enemy of the homeless.
