I've been a regular reader of these forums and the one outstanding impression I've observed is the level of denial Americans have of their health. It is so ridiculously high because of lack of education, laziness and the "subjectivity" of health, today. Everybody, here, eats "healthy" and everybody leads an "active" life (yet, almost all are overweight and taking Cholesterol and BP meds). Thus, it's impossible to relate to what their blood report is telling them.
My theory why this is so is because lifestyle diseases take years, even decades, to develop and during this lengthy gestation period you're likely to feel "fine". Thus, when a doctor declares your fasting blood glucose reads over 125 or the biopsy comes back positive or your coronary arteries are blocked 90%, the first response is, "Aw, you're crazy! I feel fine!" Of course they do! Who can tell the difference between a systolic pressure of 150 vs a normal 120?
We need smartphones that can read out blood pressure, instantaneously. We need toilets that can analyze for diabetes and triglycerides every time you take a crap. We need surgically implanted pedometers that will tell you to get off your a$^ and move if you don't take enough steps at intervals throughout the day.
And, of course, we desperately need breathalyzer tools that can detect colon and other cancers.
