Use the above link to listen to a question and answer Webinar, from February 2016, by the Lung Association in the USA. It runs for little over a half hour but if you can get even one good tip of advice from it, it is good. Another Webinar starts shortly after this one. These are shown on UTUBE and there are others to listen to on the right of your screen.
I hope this information helps everyone. Just thought you should know about it.....
(I guess the link will not go on here, instead it shows the Webinar and I don't know how to put the link on here?)
