i will offer this link one more time. published science invalidates the use of masks.

on the other hand, what are some obvious effects of mask wearing?
-reduction of oxygen intake, increase of carbon dioxide intake, therefore an immediate and deleterious upset of the balance of gases contained in every breath.
-inability to clear toxicity via exhalation, re-uptake of co2 and particulates
-constant inhalation of mask fibers having unknown and possible toxic effects
-shaming by covering of face and separating people, eliminating normal interactions
-constant fear emphasis, with well known damaging consequences
who would want and mandate these effects, and why?
