Hi actually seen the sun today for about 20minutes Ha Ha Even went out with no mack just a short coat and of course an umbrella. Went to Tai Chi this morning I would reccomend it. I have been doing it for just over 2yrs There are different forms I do Chen style 19 Form. The slow pace and breathing technique helps the COPD and the relaxation helps.It also helps balance. So if your up to it give it a go.
