Hi Ray
The Doc is right,as you know I also have COPD,but it is'nt so bad,yet.

I quit smoking years ago and it is correct,the exercise does help,and although you won't feel any benefit
at the start,it will get easier to breathe.I know It works for me.

My Doc used to say I had done more than medicine could do, just by stopping smoking.

Three steps forward one back and you WILL get there.Each time you feel breathless,stop and rest
until you recover,then carry on.

And yes,you are supposed to feel breathless,the idea is to make the heart and lungs work.

Sorry for preaching at you,do these things and you can feel better,promise.

Alan
