Well I’m not sure how old your mother is, but I remember seeing this video in my grandparents house, every single person in that room was smoking. Even the priest. That’s how it was back then. Everybody smoked, so people were exposed to smoke in The workplace, bars, you name it. It wasn’t until the 80s when they actually banned smoking in California. That was the first place it started, no smoking inside bars. So based on her age, I would say respectfully, she could have been exposed to a great deal of secondhand smoke. But none of that really matters now… We have the power of prayer, and a mighty God! Let’s just pray and see what God has in her life! God bless you Lucio and I hope that you have a fantastic day!
