Hydrogen, from reading your posts it almost seems as if scientists know nothing about anything.
By the way, the bolded part is misinformation. Among causing other cancers, smoking has been most strongly linked with lung cancer, and has been attributed as the cause of nearly 90% of all cases, especially the more deadly non-small cell lung carcinoma and further especially the cases that have worse prognosis. As far as there is certainty in science and medicine, the link between smoking and lung cancer is probably among the most certain.
Another piece of misinformation/mis-reasoning further up: while blood cholesterol level (more strongly, the levels of HDL and LDL) has been definitively linked to increased risk for heart diseases, of course there are other risk factors and markers that are also involved and monitored. And you asked what if someone with a healthy diet has increased cholesterol level? Then he should be screened for familial hypercholesterolaemia or other genetic or acquired defects in cholesterol metabolism.
On the contrary, in medicine fitness is generally defined by cardiorespiratory fitness (CRF), which is measured at clinics with treadmills and walking tests and other controlled exercises. Research in the past 4 decades in different countries, across all ethnicities and age groups and for both gender has consistently shown that CRF is inversely associated with coronary heart diseases, other cardiovascular diseases and mortality from all causes, independent of and in addition to risks from smoking and drinking, etc. If we ever need an objective standard, CRF will come as close as we can get. (but see below)Again, your suggestion indicates that there is no standard or clear attributes for fitness, and as a result, no definition. You are presuming that any set of assumptions of what fitness is are natural. That is incorrect.
Additionally, are there set standards of fitness for every single ethnicity, gender, age group and lifestyle? No. None. Besides, how would you go about calculating the fitness of a woman of one mixed ethnicity and a certain lifestyle and a man of another mixed ethnicity and race, and his own specific lifestyle? Do you have clear and complete health knowledge concerning differences between all genders, ethnicities and age groups? Do have similar knowledge that pertains to every known 'lifestyle' that people engage in? You don't; no one has such knowledge.
As for incentive to change, change to what? You still have not defined what fitness is.
To say we need to know all the root causes of diseases before we can decide on preventative or diagnostic criteria means we can basically throw out all of medicine, because we are never going to know every cause of any disease. All we can do is know with a certain confidence level that a certain number of factors will have whatever probability of causing the disease, and base our decisions on that.Your point is not clear here. If you are suggesting that fitness be related to the appearance of disease in a person, then you should know all the possible root causes of these diseases first. Smoking increases the risk for lung cancer, but there are still a very large number of people who get lung cancer who never smoked. There are also smokers who never get lung cancer (the majority). People can lead what is presumed to be very healthy lives and still suffer from any one of the above afflictions.

That is correct (the original quote by von Holhenheim was "All things are poison and nothing is without poison; only the dose makes a thing not a poison"), but it's not just the first rule of ecotoxicology, it's the first rule of all of pharmacology-toxicology.More confused thinking on your part. Remember, I was the one who informed you that everything is toxic in large enough quantities. That's literally the first rule of ecotoxicology.
I have less of a problem with Keithz' original suggestion of setting athletic exit requirements for high school, because to some extent it can serve as another (arbitrary) benchmark that, like academic performance (and "discipline scores" and mandatory arts instructions in certain Asian education systems), correlates with commonly perceived notion of a "well-rounded" education. But I disagree with a punitive "fitness tax", not because "fitness" cannot be defined objectively (it can), but because of the myriad socioeconomic factors that are hard to control, and especially the genetic components of diseases that are not yet fully worked out. Perhaps it might be more acceptable if one day personal genomics is routine, and "all" (though absolutes are not generally accepted in science) the genetic associations are understood well enough such that exemptions or exemption percentages can be set for every predisposing genes with their respective contribution (eg, if you have genes A, B and C which have x%, y% and z% association with obesity then you get an N% deduction from the fitness tax). But this would be a rather pointless logistic nightmare for which the effort and investment is probably better spent on other social programs or health measures, and is also unjust because it awards/penalizes people for their genetic makeup.You still have failed to define what fitness is, and you also have neglected to state who you would see doing all this policing over the bodies of people. Rather than to presume to answer for others, try describe how you would regulate and police the bodies of the entire population.
