The Army’s 2016 Study of the Iraq War: Still Unrealeased

The Army stymied its own study of the Iraq War. Gen. Ray Odierno, then Army chief of staff, ordered an unvarnished history in 2013, seeking to record the lessons of the conflict before memories faded. A draft was finished in 2016. It has yet to be published.

From reporter Michael R. Gordon:

Two big problems with many official Army histories are that they avoid controversy and are published so many years after a conflict they are little use to anybody other than professional historians.

A history of the Iraq War by an Army study team avoided those pitfalls. In a letter last year to the Army leadership, Conrad Crane of the Army War College praised its “almost brutal candor.”

But those very strengths made it a hot potato for Army officials. A plan to distance the service from the study was dropped after The Wall Street Journal started asking about its status. It will be published by the end of the year with forewords by Gen. Odierno and current chief of staff Gen. Mark Milley.

The Exercise That Helps Mental Health Most

Certain fitness routines do more to help avoid depression, stress or other emotional problems, new research finds

Researchers looking at the link between physical activity and mental health found that team sports fared best, followed by cycling, either on the road or a stationary bike.

.. It found that physical activity typically performed in groups, such as team sports and gym classes, provided greater benefits than running or walking.

.. People who played team sports like soccer and basketball reported 22.3% fewer poor mental-health days than those who didn’t exercise. Those who ran or jogged fared 19% better, while those who did household chores 11.8% better.

.. In a secondary analysis, the researchers found that yoga and tai chi—grouped into a category called recreational sports in the original analysis—had a 22.9% reduction in poor mental-health days. (Recreational sports included everything from yoga to golf to horseback riding.)

.. The researchers also found that those who exercise between 30 and 60 minutes had the best mental health, with 45 minutes the optimal duration. Exercising three to five times a week correlated with fewer dark days.

After Studying the Lives of 724 Men for 79 Years, Harvard Reveals the 1 Biggest Secret to Success and Happiness

.. researchers concluded that close relationships are what make men happy, and that social ties shield people from life challenges while improving mental and physical health.

.. It turns out that flourishing in life is a function of close ties with family, friends, and community. It had nothing to do with fame, wealth, social class, IQ, genes, etc.

.. Social connections are good for us; loneliness really kills.

While calling loneliness toxic, Waldinger said social connections made people happier and physically healthier. It made them live longer too.

On the other hand, he also said:

“People who are more isolated than they want to be from others find that they are less happy, their health declines earlier in midlife, their brain functioning declines sooner and they live shorter lives than people who are not lonely. And the sad fact is that at any given time, more than one in five Americans will report that they’re lonely.”
