Yeah - It sounds stupid at first, but think about it. I'll bet we're getting "second hand alcohol". But no one thinks about that. I'm just curious.
I do get your point, and I totally agree... the thing we should most be complaining about are radio waves... the exposure to pulses and cell signals and and and.. this is going to be in the news some day soon, trust me, but you can't see these.
Vapor, you can can see... and it looks like.. wait for it... SMOKE....
The second hand alcohol study would be fun to see... I would absolutely volunteer to be a test subject... lol
