Japanese have been wearing masks for ~70 years. Their flu incidence was consistently higher than the U.S. until they started an aggressive vaccine campaign ~15 years ago. Masks don’t work and never have. As for medical facilities, the anti-science behavior of the medical establishment has been one of the greatest eye-openers of this eye-opening pandemic.
Aviation safety is driven by objective data, not “expert” opinion. As just one illustrative example, we adopted checklists in the early 1940’s because we learned that even the best trained pilots can, and do, err when faced with complex tasks, especially in a high stress environment or when complacent. Most docs still don’t use them. Beech Bonanzas we’re often known as Doctor killers not because the planes were dangerous but because their pilots had egos and wallets bigger than their skills warranted. It’s as good a metaphor as any for the reasons to question the opinions of the medical profession.
