The laws we have didn&apos;t get passed because the public demanded protection. They got passed because industry groups pushed hard for them, as a way to lock out potential competitors.&lt;p&gt;A system actually designed to prevent harm would look quite different.&lt;p&gt;Preventing the use of a good treatment (type I statistical error) &lt;i&gt;is just as bad&lt;/i&gt; as allowing a bad treatment (type II statistical error). A balanced regulatory regime would make both kinds of errors with about equal probability. Our current system is so heavily biased toward preventing type II errors that we accept a vast number of type I errors.</text><parent_chain><item><author>DanBC</author><text>Intestinal flora are complex.

The advice to eat dirty vegetables or even start walking around barefoot in the dirt or drinking pond water or whatever &quot;natural&quot; activity you can think of is VERY DANGEROUS.&lt;p&gt;&amp;#62;The reason is not all parasites are &quot;old friends&quot;, only some of the ones that are commensals that we co-evolved with. Getting toxoplasmosis from a cat, or a zoonotic helminth from dog shit or a dead raccoon or a pig tapeworm will do your immune system no favors and could even kill you.&lt;p&gt;&amp;#62;DO NOT PLAY AROUND WITH THIS CONCEPT UNLESS YOU ARE ABSOLUTELY CERTAIN WHAT YOU ARE DOING.</text><parent_chain><item><author>DanBC</author><text>Intestinal flora are complex.
