Tom Cruise: Hottie or Fatty? by Dan Mindus
Tom Cruise: Hottie or Fatty?
By: Dan Mindus Newspaper: Orange County Register
If Tom Cruise had been accidentally decapitated in the making of the Last Samurai, he would have become one more victim of our "obesity epidemic." Sound strange? Welcome to the politics of fat, where bathroom scales can be tax-deductible, lawyers are lining up to sue anything rumored to contain calories, and the press has fed us a steady diet of hysteria and hyperbole.
The first thing you need to understand is that in our twilight zone of fat hysteria, he is officially obese. That's based on the Body Mass Index (BMI), a measurement that separates us into government-approved, overweight, and obese categories by taking into consideration only our height and weight. A BMI of 30 or more makes you obese, and at 5-7, 201 pounds, Tom Cruise has a BMI of 31.
According to the BMI standard, 61 percent of Americans are overweight or obese. You have probably heard that number. Along with the claim that obesity costs the United States $117 billion a year and kills 300,000 Americans annually, it is one of the three most commonly cited figures associated with our so-called obesity epidemic.
But it's more like an epidemic of bad statistics. All three of these numbers are seriously flawed.
Fatty Cruise is in good company. Thanks to the absurdities of the BMI yardstick, Sylvester Stallone (5-9, 228 pounds, BMI of 34) and Mel Gibson (5-9, 214 pounds, BMI of 32) are also "obese." So was Mark McGwire (6-5, 250 pounds, BMI of 30) the year he hit 70 home runs. And if politics is your thing, you'll be interested to know that the new governor of California (6-2, 257 pounds, BMI of 33) is obese, too.
Here's how the Centers for Disease Control and Prevention explains these counterintuitive results: "Overweight may or may not be due to increases in body fat. It may also be due to an increase in lean muscle."
It's not just full-blown obesity that has been bungled by numerical hocus-pocus. 39 million Americans went to sleep one night in 1998 at a government-approved weight, and woke up "overweight" the next morning, thanks to a change in the government's definition. That group includes presently "overweight" (BMI greater than or equal to 25) movie stars like Will Smith (6-2, 210 pounds, BMI of 27) and Pierce Brosnan (6-2, 211 pounds, BMI of 27). Michael Jordan (6-6, 216 pounds, BMI of 25) and Cal Ripken Jr. (6-4, 220 pounds, BMI of 27) were also "overweight" at the height of their athletic powers. And so is our ultra-fit President Bush (6-0, 194 pounds, BMI of 26). Moreover, the standard that we abandoned in 1998 had the virtue of distinguishing between men and women--something we now do not even attempt to do.
So what does Tom Cruise's imaginary swordplay mishap have to do with obesity? Chalk it up to more bad statistics. The regularly recycled factoid that excess weight causes 300,000 deaths a year bizarrely assumes that if you die while overweight, you die because of that excess weight. As insane as it sounds, if Cruise were to kick the bucket for any reason, his death would count toward the mythical 300,000 total.
The respected New England Journal of Medicine knows this is bogus. It maintains that the 300,000 figure "is by no means well established. Not only is it derived from weak or incomplete data, but it is also called into question by the methodologic difficulties of determining which of the many factors contribute to premature death."
Nevertheless, this statistic finds its way into nearly every discussion of obesity--as does the spurious claim that obesity costs Americans $117 billion per year. The source of this figure: a single study published by the journal Obesity Research in 1998.
This study had serious limitations, as the authors themselves admitted. They acknowledged that their methodology resulted in the "double-counting of costs" which "would inflate the cost estimate." There's also this stunning admission: "We are still uncertain about the actual amount of health utilization associated with overweight and obesity. Height and weight are not included in many of the primary data sources."
But even if they had good data to work with and somehow controlled for the double (and even triple) counting of costs, these researchers still would have reached a unrealistic conclusion. Why? They used the wrong definition of obesity.
A BMI of 30 or more makes you obese, but the authors of this study for some reason decided to set the threshold at "BMI greater than or equal to 29." Thus they erroneously included the economic cost of individuals with a BMI between 29 and 30. A small error? Not at all. That covers more than ten million Americans, including Bruce Willis (6-0, 211 pounds, BMI of 29), Brendan Fraser (6-3, 234 lbs, BMI of 29), and George Clooney (5-11, 211 pounds, BMI of 29).
$117 billion cost. 300,000 deaths. 61 percent overweight or obese. All wrong. Unfortunately, these bad statistics are the shaky ground on which a growing number of activist groups seek to build their nutritional utopias.
The primary cheerleaders of inflated obesity figures are the self-described "food cops" at the Center for Science in the Public Interest, who advocate "sin" taxes on foods they don't want you to eat. An animal rights group called the Physicians Committee for Responsible Medicine uses the bad stats to force a vegetarian diet down our collective throats. And then there's the American Obesity Association, which aggressively promotes these concocted numbers in its quest to have obesity classified as a disease for the financial gain of its pharmaceutical industry clients.
Common sense tells you that obesity is no more a disease than couch-potato-itis; that replacing milk and chicken with tofu won't magically shed the pounds; and that Tom Cruise isn't fat. But obesity fears and inflated statistics have tipped the scales against sound judgment.

Technology in your context
Students complete course survery and participate in focus group meetings. Such activities can produce robust data relating to their perceptions on the quality of their courses. We have been using email as the main mode of communication with students for over a year - feedback so far has been very good. Students enjoy the convenience of being able to communicate with staff at their own convenience. They can send work, ask questions, inform of absences, and get noticeboard information through their email accounts.
I am aware that at the present time all of us at the college -teachers and students - are in a transitional phase. Moving slowly away from traditional teaching/learning delivery methods towards something new but not yet identified. There is no doubt in my mind that this can only be a positive move towards a better place. Why? Because when the ability to communicate becomes easier then the ability to reach an agreed teaching/learning outcome becomes much easier too. We, at the college, are way behind many of our counterpart colleges but things are moving quickly. Soon our VLE will be used by students and staff alike.
Outlook was adopted by our college several years ago. At that time staff communicated with each other and students using traditional methods ie noticeboards, handouts, phone calls, letters etc. At first many staff said that emailing would never 'catch on'. It's funny to think back to those days. No one looked at computer screens in our dept then. Today, its the first thing that staff switch on and if you walk into our office at any time you would see a host of faces peeled to their screens.
The new technology does not embody the assumptions about the nature of teaching and learning in HE. On the contrary, it is slowly dismantling them and the 'traditionalists' in my area are very concerned. Why? Essentially because, communication is becoming more and more informal and information is becoming more readily accessible. This means that there are fewer and fewer secrets. It also means an even greater demand for teacher accountability.
On the 'flip-side', more efficient communication, has meant that students/learners cannot avoid their responsibilities by saying things like, 'I didn't get that message' or 'I couldnt contact you to tell you that I couldnt attend' etc.

How much more complicated can it be?
I've worked in a College of Further Education for the past 14 years - and in a Secondary school for 6 years before that. I have read some stuff in my time and have never given up in the quest to discover the learning and teaching 'Holy Grail' ie what are the secrets that would make me the perfect teacher. Then I would be able to sit back and relax.
Sometimes - when younger teachers or people outwith education ask me questions about what teaching and learning is - I fall into the trap of actually trying to explain it to them. After a couple of minutes of preaching I stop myself abruptly, as if I had just caught a glimpse of myself in a mirror wearing a silly hat. I say to them: "How the hell do I know. You know just as much as me."
I have found myself doing the same thing during the first 2 blocks of this course. Both blocks of study contained some excellent literature. Richardson's compilation/lit.review of research has perhaps been the most interesting so far. I find myself engaging completely with the debate. However, it does strike me that this is actually a never-ending-debate and that everyone is correct. Vast numbers of paradigms, constructs, systems, research and literature. All with value and virtue but all just bringing us back to the same point: no two learners learn the same way and no two teachers think the same way about teaching. Even more disconscerting to those seeking the Grail is that no two teaching and learning situations are ever same.
As a learner I have experienced all 5 learner conceptions listed and as a teacher I have also experienced all 5 teacher conceptions. True, I have a rough idea of what the outcomes of most learning and teaching situations will be, and I am a good judge of which type of teaching approach may suit a particular group of learners but in most cases its nothing more complicated than being a good listener, putting the learner first and doing everything in your power to get the learner to where they want to be.
