This is just general common sense advice for literally an illness. It's not COVID-specific. If you touch your eyes, nose, and mouse, you're more likely to get infected by whatever's around.
I agree, not arguing with You. The point is I watch people on the news everyday adjusting their masks, pulling them under their nose, scratching their foreheads etc... yet I honestly have not heard a word regarding face touching for the past 2 or 3 months. Can you honestly say you have? I wasn't arguing for face touching so don't get all virtuous and preachy about my comment.
