Ward,
Their country, their rules.
I'm a light sleeper going east, so I read a lot on the 7-9 hours in the air. Having to wear a mask which fogs my readers is as bad as getting a swab pushed up my nose.
Ironic how these folks here and there who always crow about "the science" don't seem to accept the ample data on the effectiveness of the Moderna and Pfizer vaccines. I would gladly wear a government issued certificate around my neck for the sole benefit of the fearful. Alas, that and most everything else do not seem to be enough.
I so want to go, but the distinct impression is that "they" prefer we stay home.
