I smoked about two packs a day. Went to the doctor, said I had COPD – I didn’t know what COPD was. This was about 5 years ago. 2 years ago I had cancer and beat it. Still having chemo, I was on cloud 9. Then last year COPD got bad – I quit smoking for about a month now. Tired all the time, still working at 75 in security. I live in Ohio, cold weather is rough for me.
