“Maybe it helps, maybe it doesn’t, but I don’t see a harm.”
My mask wearing had been for a few minutes here or there. Where they draw blood, for example, they won’t if you don’t play by their rules. Some Publix employees act like that famous scene in “Invasion of the Body Snatchers.” Then, one day, I had to wear it on and off for several hours. (Lowes, the bank, Costco...) Suddenly, I thought I was having a heart attack. My chest felt like I had a cement block on it. Then, from decades ago, I remembered what an asthma attack felt like. I had to get an inhaler. Now, every time I put on a mask, I have an asthma attack.
God didn’t create us to breath our own exhaust.
