> I mask because I am worried about dangerous substances entering my body that could cause harm, and a filter can only help provide protection

> I inject any random mystery thing I can, dont pay any attention to whats in the thing, dont assess if it works for me or is in any way relevant to my health situation, ignore the motivations and credibility of those who demand I take it, and are completely careless about personal risk taking in general

Pick one.

Why would you ignore stuff entering your actual bloodstream but heavily police and guard other more protected parts of your body and points of ingress at the same time?
