Remember over 150,000 people die from various causes in the world every day. Over 22,000 people die (many are children) die from hunger everyday. Over 35,000,000 people dies from HIV/AIDS. We have less than 7,000 deaths from COVID-19 as of today.
I really do not enjoy wearing mask for 8~9 hours on the plane.
Also, I was expected to wear mask when I was in Japan and Korea.
It may help but I do not want to go places where you need to wear mask.
That is one of the reasons why I really considering not to go to Japan next month.
