I have to wear a mask for work. My boss and I don't think they're necessary, but she owns a small business and can't afford to lose more business (we teach and tutor kids).

I had the plastic visors but they kept giving me a headaches so three weeks ago, I switched to the masks. Two weeks ago I had trouble breathing. Last week, I got a throat infection. I came back to work Monday and decided to go back to the plastic shield this past Wednesday to see if it would clear up.

It's Friday afternoon now, and it's finally clearing up.

I eat well, exercise regularly, and only drink water and plain green tea.

These masks are a hazard and there's enough data to back it up.
