Are lockdowns justified?

[awty]

Our breath is moist, because we breath out water from our lungs.  This is a mix of water vapor and fine aerosol.  When you breathe on a mirror, the moisture from your hot breath condenses on the colder mirror.

Talking is a great way to generate larger micro droplets -- the vocal chords literally spew out micro-droplets (as likely does the mouth).

Then why do statistics show you are far more likely to get COVID from somebody who has symptoms than from somebody who is asymptomatic (like the vast majority of children who get COVID are)?

Supply those statistics.
