To All,
It really doesn't matter whether you smoke or not, here is some interesting reading pertaining to the subject. It opened my eyes on the subject even though I gave up smoking years ago. Plan on spending some time to digest the information especially the "forward". I found the material fascinating and easy to read. After all, one does not have to close off the brain to available information. Have a nice Sunday!
