Having a minor cold, sniffles, I decided to wear a surgical mask for practice and found it was uncomfortable and steamed up my glasses. When there were major forest fires in Northern California a couple of years ago, I wore an N95 mask and it was very uncomfortable and I could only wear it for an hour at a time. I don’t understand how the Japanese can wear masks all day at work.
Very interesting and informative article westcoastdog, thank you! 🙂
