A 52-year old revealed that she is suffering from a chronic obstructive pulmonary disease even though she has never smoked in her life.

“Nobody realised the devastating effects of smoking 50 years ago, they just thought it was fashionable. I’d get up in the morning and the first thing that would hit me when I walked down the stairs was the vile smell of smoke. I would cough and cough until I was nearly sick” she said.
Mitchell added that her lungs are now operating on just 22 percent of their capacity and she needs an oxygen mask to breathe.
