Did you know that second-hand smoke is the most preventable disease?

I was shocked to read that 600,000 people, worldwide, die annually from second-hand smoke. Nearly half are women and 28% are children. In our early marriage, we were not aware of the dangers of second-hand smoke. No one told us. Our children survived and we were blessed. No so, for our granddaughter, my wife i raised. She developed asthma and was sick a lot. A Vanderbilt doctor told us to stop smoking in our house, that it was killing our granddaughter. This we did. We called a cleaning company and our home was thoroughly cleaned of tobacco residue. We now smoke outside. Question: I wonder how many people still smoke inside their home and are endangering their children and other family members?
