Head Trauma and Learning
November 23, 2012
Researchers at my alma mater have joined their voices to the growing chorus of concerns about the effects of repeated blows to the head.
A study of the cognitive effects of head impacts on members of Dartmouth College football, hockey, track, crew and Nordic ski teams compared before and after season results on learning and memory skills. Participating athletes also came from Brown and Virginia Tech.
-
22 percent of athletes in contact sports had lower results on learning and memory skills tests after their season.
-
Only 4 percent of athletes in non-contact sports posted lower test results.
The researchers caution that it is unknown at this point how long these negative effects may last, but they also note there is some correlation between test results and how hard the athletes were hitting heads.
This adds to the mounting evidence that rules writers, program sponsors, coaches and officials must look for and implement a variety of measures to reduce the frequency and severity of head impacts in both practice and competition in all sports.
Out-Punting Our Coverage
March 19, 2013
Any traveler to the Atlantic coast of any Central American country will witness firsthand the arrogance of the human race.
Strewn along almost every shore is the waste of nations outliving their means. Plastic in all shapes and colors, from products of all types – bottles, toys, sandals, tools.
Island nations to the east, unable to cope with the volume of their waste, cast it off covertly under cover of night. Oceangoing vessels large and small heave it overboard.
My wife puts it this way: “We’ve gotten ahead of ourselves.” Humans have fantastic abilities to create, but we do so without conscience, without caring enough about consequences.
This clearly applies to the world’s waste problem – from cast-off containers to used cars to computers made obsolete in a matter of months. We keep producing more and more, without plans for the waste of producing new products or the waste created by making existing things obsolete.
In the Pacific Ocean, a mass of trash the size of Texas is circulating as if there were a drain. But there isn’t one. No easy answer to flush human waste – the excrement of our greed – to some other place where it will do no harm.
In Chinese cities today the air, water and land are toxic – much as it was in developing US cities around 1900 – as China takes its turn to poison its people in the name of progress.
That we can do something doesn’t mean we should do it. In sports terms, the human race has out-punted its coverage, and the consequences are far more dire than a punt return for a touchdown.
