What masks do for a living?
Take one outside. See your breath? The condensation contains virus. Even from a healthy person and not Covid 19
Put on the mask. See the limitation of condensation distance?
Breathe, talk, yell, scream. Do you see the difference in distance between the two? Remember the CDC recommendation for distancing?
Why is this even a subject of argument?
Amplitude x Time of Exposure
Same physics for all common viruses illnesses

Canada is no longer shipping test kits as the ones out in the community are aging out.

I have already been sick twice since the beginning of the pandemic. My sense of smell and taste got a lot worse after that.... Various supplements from Canadian Pharmacy and lots of fruits and vegetables are improving it, but overall I don't think I'll ever get it back 100%. It is interesting to find out exactly where this virus came from...

In the case of "long" expired test kits are the trends and tendencies learning toward false positive or false negative results?
Thank You.
