Unpleasant reversal

In preliminary mortality data out this month from CDC, a few issues stand out. First, estimated life expectancy at birth decreased (by 0.1 year) between 2014 and 2015. Granted, a single year does not a trend make, but some of the underlying details are downright disturbing:

• Drug overdose mortality rates are up (see details for young adults)
• Suicide mortality is up (see details for young adults and for teens)
• Infant mortality (especially unintentional injuries) are up
