Just to add an example my sister is four years older than me, about 130 pounds, and very very active. She gave up smoking probably 30 years ago. She had some breathing issues and they told her she had something with a fancy name and put her on oxygen. She lives in Florida and we talk daily but i hadn’t seen her for several years except for a few weeks during the summer and Christmas. I told her there was no way she had what they were saying and I told her to tell the doctors I used a Cpap nightly. They tested her and she needed on. She quit oxygen two days later and loves her Cpap, and me.
