Check this out.. I smoked for 20 years, quit 2 years ago. I was still caughing and getting out of breath quite easily. I just had my annual physical (yes, I was diapered) and I brought this up. My doctor ordered Blood test, ECG and chest X-rays. Blood test came back with high red blood cell count so she ordered a Lung Function Test. The results for that showed that I have mild COPD. Got a prescription for a inhaler and feel a lot better. How long did this all take, 2 weeks. How much did it cost me ZERO. Yes, I do pay a bit more tax than you do in the states, But I don't pay anywhere neer what you pay for your private health care. Remember, the american system is profit based with share holders who demand growth so they make more money. The Canadian system is Not for profit, no one gets rich off of it.
