Zig-zag health advice

Who in the world hasn't been deluged with often confusing and contrary information since this pandemic officially began in late 2019 in Wuhan, China?  Lockdown "flattens the curve."  Masks block spread of infection.  Or do they?  Social distancing (6 feet) is outside the airborne range of the virus expelled when coughing.  But studies say viral particles are airborne up to 12 feet.

Yes, but you will forever be vulnerable to this virus if you don't get exposed to it and develop natural antibodies.  Why wait for a problematic vaccine when your (healthy) body will develop antibodies on its own?  Studies show that is precisely what has happened in Sweden, a country that did not lockdown or mandate face masks.
