My stay at home mother was a smoker. She died at the young age of 42. I spent a lot of my summer outdoors. I developed cabin fever during the winter months and had to get outdoors.
I don't think my dear mother's smoking affected my health, but her death from breast cancer affected me in other ways.
You be your own judge.
It's the luck of the draw, Buddy.
I just lost my best friend to lung & liver cancer at age 47. She didn't smoke and I can count on one hand the glasses of wine she's had in 25 years. It was genetic. Her Mom died of brain cancer and her father of liver cancer. She also lost a sister to liver cancer.
Her two remaining siblings are pretty much counting their blessings and their days.
We should all live that way. :)
