Like " Hi Pegsy My Father was a smoker, I spent a lot of time with him in a closed car. I used to have a lung problem if I caught a cold. However I embarked on as healthy of a lifestyle as I could figure out over the years. I haven't had a cold, virus or bacterial infection in 8 years. If I got one, then I would know if I still have a lung problem. I credit my good fortune to not eating meat that has been fed antibiotics in their feed everyday along with a healthy, low carb, whole foods diet, and regular exercise.. I started that 8 years ago and have had no infections since that. Being diabetic, I used to get bacterial infections on a regular bases, along with colds etc.. "
