I have several people in my family who demonstrate various levels of hypochondriasis. Imagine the nonsense over gluten-free and every other fad diet of the last 30 years, non-specific symptoms, alternative &quot;medicine&quot; and that&#x27;s two or three people in my immediate family. Now let them start ordering their own blood tests and it&#x27;ll make the anti-vaxing movement look like a cultural blip.<p>Most people simply aren&#x27;t smart or informed enough to understand things like &quot;false positives&quot;.
