Hi again TimU - the second article explains some of the differences between COPD and asthma. You can find it here: https://copd.net/clinical/asthma-copd-differ/.
The way this aspect of the website works, only one link at-a-time can be posted in these replies. That is why my reply was broken into two posts.
I do hope you find this material to be helpful. Please do check with your physician about your concerns and please keep us apprised of your progress.
All the best,
