Why I Stopped Watching the NFL

After reading this New York Times story, I stopped watching National Football League games.

The gist of the story is that for years the National Football League has ridiculed studies done by outside researchers trying to determine what, if any, affect playing in the NFL has on cognitive behavior. Do all those hits and concussions lead to Alzheimer’s-like diseases and other mental problems for players?

At least one survey of retired NFL players conducted by the University of North Carolina’s Center for the Study of Retired Athletes found a correlation between playing in the NFL and a number of cognitive impairments. Not to worry, though, as an NFL official helpfully dismissed the study as “virtually worthless.”

So the NFL commissioned its own studies, including a recently completed survey of retired NFL Players. That study found NFL players were much more likely than men who didn’t play in the NFL to suffer from Alzheimer’s disease or similar problems.

The NFL’s response? Mostly to highlight the shortcomings of the study. And make no mistake, this survey is not perfect. For example, the survey asked players whether or not they had been diagnosed with Alzheimer’s or a similar memory problem, but it didn’t directly diagnose them — some of the players could be mistaken. Of course NFL players were asked the same questions that the National Health Interview Survey asks of the general public which was used as the baseline rate of incidence to compare the NFL rate to.

Similarly, it could be that the correlation is not due to dangers on the field, but rather the access that elite athletes have to health care off the field: former NFL athletes might be diagnosed with dementia at a higher rate because they have access to better medical care and their physicians are more likely to look for dementia given the violent nature of the sport.

Certainly this study calls for more rigorous follow-ups. But in general the comments of the NFL spokesmen and their hired guns make it clear that the NFL doesn’t really want to know whether or not playing football causes cognitive problems unless the answer is “no.” The fact that the NFL has only begun looking at the problem in the last few years and then resorted to trashing one of the few completed studies it actually bothered to fund, suggests a business that genuinely sees its employees as disposable cogs.

I’m not saying you should stop watching the NFL, just that I can’t stomach the spectacle anymore given the league’s obvious indifference to the legitimate health concerns of its players. That’s far more offensive television than Janet Jackson’s exposed nipple.

Augmented Reality Contact Lenses

Babak Parviz has written a fascinating overview of the challenges and promises of creating contact lenses with augmented reality features — think contact lenses driven by a portable device that effectively add a computer-generated overlay to the real world.

Parviz knows of what he speaks as the University of Washington professor and his students are already building one-off custom lenses that incorporate a single LED powered wirelessly by RF.

These lenses don’t need to be very complex to be useful. Even a lens with a single pixel could aid people with impaired hearing or be incorporated as an indicator into computer games. With more colors and resolution, the repertoire could be expanded to include displaying text, translating speech into captions in real time, or offering visual cues from a navigation system. With basic image processing and Internet access, a contact-lens display could unlock whole new worlds of visual information, unfettered by the constraints of a physical display.

Parviz also notes such contact lenses could be used to gather health and other information such as, for example, glucose levels for diabetics.

Parviz nicely lays out both the possibilities such a device would hold, but also the very real challenges in building one, especially since many of the substances that are routinely used in electronic devices are toxic, which starts to become a problem when you’re talking about putting them in nearly direct contact with the eye.

Personally, I’m hoping I live long enough to see something like this become common, though if texting and driving is a major problem, imagine what that will be when you can have YouTube streamed directly to the surface of your eye.

MacLeans on Albino Killings in Tanzania

MacLeans ran a brief summary of the current status of the prosecution of men accused of murdering albinos in Tanzania. Albinos are targeted in Tanzania and other African countries because it is believed their body parts have magical and/or medicinal properties. MacLeans reports that in October three men were sentence dto death for the killing of a 14-year-old albino boy whose body was then chopped up into pieces, presumably for sale on the black market.

It also reports on a particularly recently grizzly murder of a young albino girl,

An equally barbaric case is also garnering national attention: Mariam Emmanuel, a ?ve-year-old girl, was butchered by a group of machete-wielding men in Mwanza. The culprits divided the girl’s body up among themselves and drank her blood while her siblings watched.

Unfortunately, while this conviction (though not the death penalty) represents progress, this is apparently the first time since the wave of albino killing began in 2007 that anyone has been convicted of a crime related to the murders in Tanzania.

Under the Same Sun is the main organization currently addressing issues faced by albinos in Tanzania, including the horrific murders, and has a petition urging that more be done to stop the murders. It also accepts donations.

Andreas Gohr on the State of the DokuWiki Community

I am a huge fan of DokuWiki, the open source Wiki software developed by Andreas Gohr and others, and have multiple installations of the software on my webserver. Gohr recently posted on his blog about the current status of DokuWiki which can be summarized as: too much stuff is dependent on Gohr.

Gohr’s been trying to do more to foster a larger DokuWiki community around the software and has a fair list of things he’s been trying to do over the past few months both to technical and non-technical to create more diversity in the DokuWiki community.

Personally, I promote DokuWiki at every con and other geek-oriented event I manage to make it to, and suggesting the software to folks looking for an easy-to-install but still full-featured Wiki.

Zombie Driver

What does the world need now? MORE ZOMBIE GAMES!

Enter, Exor Studios’ Zombie Driver in which the player drives cars around, upgrading them or choosing new cars with different features, all the while mowing down zombies and rescuing survivors. Supposed to be released sometime in November 2009, but no pricing as of yet on the website.
