I prefer the term "indestructible" to old, LOL...
Marc411 was discussing this at some point, he has collected a bunch of information the he prints out and keeps around to hand to naysayers. It is a LOT of information, LOL. Only thing is, if anyone wants a copy, you'd have to PM an email address, as a lot of it is in PDF form, but there are lots of great articles in there all collected into a nice, orderly "Here is what you need to know." I keep it around in case I run into someone who is really rude to me about vaping, but that hasn't happened yet, though I'm not a cloud chaser so I think many people don't notice, or just assume it's a cig from a distance....
