No. They don't. Well poisoning shill.
You are the liar spreading the lie. Masks significantly lower oxygen levels. Why don't you want to get an oxygen sensor and objectively measure that simple fact by yourself? Are you so dumb that you can't take a multimeter and measure voltage between two pins of the sensor? OK, you could buy ready-to-use oxygen level meter and measure. You don't believe in electricity? Or may be you can't read digits from LCD? What is your problem, tell us please, we will try to help.
decreasing blood oxygen doesn’t kill brain cells?
show your work asshole.
Youre mad because youve been wearing that fucking thing everywhere you go. Youre one of those dumbfucks driving your car and walking your dog with it tied up to your eyelids. I can tell, its turning you retarded.
So angry and aggressive you are. I'm sorry your life is so miserable. Not everyone has that experience.
