I have done a decent amount of research on the non-smoking issue. There is more manipulation of facts involved than I care to get into with you. Do a little research - it is all about money - NOT HEALTH.
Meanwhile, there is an 83 year old that lived with smoker's for 75 years, first her dad then husband, and is the healthiest person I know, next to me of course.
I watched my brother-in-law die of emphysema. He was 25 years older than my late husband, so I think he was 78 then. He had quit smoking years before, but it was too late. It was a horrible death. It is awful to feel that you are suffocating.
My aunt is 84. She has been smoking since she was 25. She has emphysema. She coughs all of the time. She has to sleep with oxygen on. She still smokes. She has almost died of pneumonia. She has to use inhalers all day. Sometimes she has to use oxygen during the day. She has trouble breathing, but she can't quit smoking because she is so addicted. She has had breast cancer.
Not everyone who has smoked or who smokes will have emphysema or lung cancer. Some people are more predisposed to getting cancer than others. We just never know. That is the scary part.
