A consistent increase in life expectancy is one of society's bedrock measures of progress. The average life expectancy of an American has increased about 30 years since 1900.
So what does it signify when for the first time in 55 years, the United States saw life expectancy decline for two years in a row, as it did in 2015 and 2016?
It means this country is killing itself, with drug addiction and suicide its methods of choice, and that Alzheimer's is a disease it cannot get a handle on.
The last time life expectancy in the United States declined two years in a row was 1962-1963, when a flu epidemic tilted the figures. The last time it declined for even one year was in 1993, and that was caused at least partly by the AIDS epidemic.
The biggest reason for the sad change is an opioid epidemic that led to about two-thirds of the 63,600 drug deaths in 2016. That's a death rate that's tripled nationally since 1999.
Another reason is a rate of suicide that's been steadily increasing for the past 30 years and left about 45,000 people dead in 2016, an absolutely staggering tally. And yet another is the fast-growing incidence of Alzheimer's deaths, which increased more than 5 percent to 116,000 from 2015 to 2016.
That so much of what is killing us seems to involve despair and mental illness and preventable life choices offers both hope and sadness. It's clear the trend is reversible. But it's also clear we need to be as committed to fighting suicide and addiction as we have been in the past toward AIDS and influenza if we are going to change that trend.
