Update: 60 Minutes Video: A Blow To The Brain -- This is Your Brain on Football

Discussions of the devastating effect of concussions are all the rage in football right now, with even 60 Minutes getting into the act.

Now comes an absolutely frightening Malcolm Gladwell piece from The New Yorker. Here are some especially interesting excerpts...

Part of what makes dogfighting so repulsive is the understanding that violence and injury cannot be removed from the sport. It’s a feature of the sport that dogs almost always get hurt. Something like stock-car racing, by contrast, is dangerous, but not unavoidably so.

In 2000 and 2001, four drivers in Nascar’s élite Sprint Cup Series were killed in crashes, including the legendary Dale Earnhardt. In response, Nascar mandated stronger seats, better seat belts and harnesses, and ignition kill switches, and completed the installation of expensive new barriers on the walls of its racetracks, which can absorb the force of a crash much better than concrete. The result is that, in the past eight years, no one has died in Nascar’s three national racing series.

Stock-car fans are sometimes caricatured as bloodthirsty, eagerly awaiting the next spectacular crash. But there is little blood these days in Nascar crashes.

Last year, at Texas Motor Speedway, Michael McDowell hit an oil slick, slammed head first into the wall at a hundred and eighty miles per hour, flipped over and over, leaving much of his car in pieces on the track, and, when the vehicle finally came to a stop, crawled out of the wreckage and walked away. He raced again the next day. So what is football? Is it dogfighting or is it stock-car racing?

Football faced a version of this question a hundred years ago, after a series of ugly incidents. In 1905, President Theodore Roosevelt called an emergency summit at the White House, alarmed, as the historian John Sayle Watterson writes, “that the brutality of the prize ring had invaded college football and might end up destroying it.”

Columbia University dropped the sport entirely. A professor at the University of Chicago called it a “boy-killing, man-mutilating, money-making, education-prostituting, gladiatorial sport.” In December of 1905, the presidents of twelve prominent colleges met in New York and came within one vote of abolishing the game.

But the main objection at the time was to a style of play—densely and dangerously packed offensive strategies—that, it turns out, could be largely corrected with rule changes, like the legalization of the forward pass and the doubling of the first-down distance from five yards to ten. Today, when we consider subtler and more insidious forms of injury, it’s far from clear whether the problem is the style of play or the play itself...

When we think about football, we worry about the dangers posed by the heat and the fury of competition. Yet the data from HITS (a system in which six sensors are placed inside the helmet of every player on the field, measuring the force and location of every blow he receives to the head) suggest that practice—the routine part of the sport—can be as dangerous as the games themselves...

Much of the attention in the football world, in the past few years, has been on concussions—on diagnosing, managing, and preventing them—and on figuring out how many concussions a player can have before he should call it quits. But a football player’s real issue isn’t simply with repetitive concussive trauma. It is, as the concussion specialist Robert Cantu argues, with repetitive subconcussive trauma. It’s not just the handful of big hits that matter. It’s lots of little hits, too. Kindle: Amazon's 6" Wireless Reading Device
