When the message is the same regardless if you are at the Kingdom Hall or watching it on Zoom, why would anybody go to a Kingdom Hall to be coughed and sneezed upon? Not to mention all of the hand shaking. One side effect of not going to meetings that I discovered is what I thought was a chronic cough went away.
Think about this. Have you ever been around someone vaping? Can you smell the fruity scent of their vape juice from several feet away? It is the same with any virus.
