Sperm, brains, and China

A new report suggests that sperm counts in men in North America, Europe, Australia, and New Zealand have decreased by half in the last forty years.  According to lead researcher Dr Hagai Levine,

“Eventually we may have a problem with reproduction in general, and it may be the extinction of the human species.”

The report doesn’t dwell too much on the why part of this finding.  Still, the implications are disconcerting.

Another  newly-released study looked at the (postmortem) brains of NFL (and other) football players and discovered that almost all of them had brain damage.  More specifically, they were diagnosed with Chronic traumatic encephalopathy (CTE), which is a “progressive neurodegeneration associated with repetitive head trauma.”  A summary breakdown of the study, as illustrated by the Los Angeles Times, looks like this:

Finally, China seems to be fortifying its border with North Korea (as described in USN&WP, Fox, CNN, Newsweek, Business Insider, and, for those who can afford the subscription, the WSJ).  All of these articles set out to explain why China is doing this.  Unfortunately, the one thing they all fail to explain is why China is doing this.  Maybe the Chinese got an advance copy of the sperm report.
