Yes and rightly so.
1) Heart rate monitors come in versions that can record data, and version that do not record data.
2) It is an excellent tool for endurance based exercise training and learning about physical health.
3) If data is collected for scientific purposes and you have not been notified, then it is highly illegal.
4) If data is collected by government agents (i.e. teachers)for other purposes, then you and everyone else here has been voting for the wrong people.
5) Don't let your kid take his heart rate monitor on this bus:

Obviously DNA can have positive effects on medical issues. These people are putting their DNA on the web. So the question is, is this science or a political stunt?
Here is an abstract from an article I found on PubMed. Can't help but draw a parallel:
Eugenics and American social history, 1880-1950.
Allen GE.
Department of Biology, Washington University, St. Louis, MO 63130.
Eugenics, the attempt to improve the human species socially through better breeding was a widespread and popular movement in the United States and Europe between 1910 and 1940. Eugenics was an attempt to use science (the newly discovered Mendelian laws of heredity) to solve social problems (crime, alcoholism, prostitution, rebelliousness), using trained experts. Eugenics gained much support from progressive reform thinkers, who sought to plan social development using expert knowledge in both the social and natural sciences. In eugenics, progressive reformers saw the opportunity to attack social problems efficiently by treating the cause (bad heredity) rather than the effect. Much of the impetus for social and economic reform came from class conflict in the period 1880-1930, resulting from industrialization, unemployment, working conditions, periodic depressions, and unionization. In response, the industrialist class adopted firmer measures of economic control (abandonment of laissez-faire principles), the principles of government regulation (interstate commerce, labor), and the cult of industrial efficiency. Eugenics was only one aspect of progressive reform, but as a scientific claim to explain the cause of social problems, it was a particularly powerful weapon in the arsenal of class conflict at the time.
I have not seen the original either, and I make it a habit not to trust what is being said otherwise. Anyway, the whole free-living measurement is a nasty situation to deal with. I have not looked at the literature on children, but I am pretty sure they have attempted to apply the bell curve to "typical children activities" vs. caloric expenditure via a regression equation. I seriously doubt that they have individual curves for each participant, although they may have. The general assumption is that children are on their feet for most of their physical activities.
I think one of the problems here is the fact that sport and exercise are subsets of physical activity. It is quite possible that kids who do not participate in sport are just as active over all to those that do. With adults, you are on your bike or you are on the couch. Not necessarily the case with children though.
Accelerometers, in terms of physical activity measurement, work based on total body movement, in this case walking, and more directly, the small vertical movements produced when walking (this depends on the model used - some are triaxial). You would not use accelerometers to measure power output on a bike, just as you would not use the various power measurement devices designed for bikes to measure caloric expenditure of walking and similar activities. The right tool for the job. In terms of accuracy, accelerometers are as good as most of the other tools used to assess physical activity, which is moderate. The exception is VO2 - not practical in this case. Your first statement is likely right, but free-living studies, which this appears to be, unlike that of power measurement on a bike, introduce a lot of variables that are hard to control for.
That's because you are improperly using the measurement device.
Accelerometers are becoming more common in exercise science because they have been shown to have a moderate level of correlation when used to predict caloric expenditure of whole body movements. This is about the same as the other common methods used to predict energy expenditure. When coupled with heart rate, the accuracy improves greatly. Measurement of VO2 is the gold standard but is impractical, particularly in group studies of free-living children. There are still many issues to be ironed out in the use of accelerometers for the purpose of caloric expenditure, so I too question their findings.
I saw this idea tank and someone lost their job over it. This guy required new incoming MBA's to have new laptops, not to mention they required exact models for support reasons. Some students REALLY resented buying a new one. Then it got better. Some of the faculty would not allow laptops in their class. This resulted in some students leaving the computer at home while others brought theirs to school. So then the ones who left their computer at home started trying to use the computers of the students who brought them. This created hate and discontent. It also created a new position to fill when the staff member was told to find a new job.
Sarcasm aside, MS has gotten better and I like the interface, but the back end needs some work. As far as stability, I've had 2 Linux servers run from power outage to power outage, one had an uptime of over 580 days, the other ran for over 630 days. These numbers are not all that uncommon, though it's not in the best intrest to go this long without a kernel update. I'm not as anti-MS as I sounded in my first post, but I think MS has earned their black eye.
OS wise windows never comes close. No secret there. Go ahead and get OS full of holes with the latest Win version of 2003 server, make the adjustments to working in this world, then when you get all comfy with the new setup, MS has a new version of vaporware on the horizon called Longhorn (or whatever it is this year) waiting for you to start over with.
I suppose if your applications are weak on the 400 you will need to make the jump.
Best of luck.

Ditto in Tuscaloosa. You can bust your ass slipping on them in the grass, like ball bearings on a concrete floor.
they take 100 years to show up? Are we still experiencing a warming trend?

Use it. I kinda like google/bsd nowadays.
