I just found a site that focuses on a lovely young woman , Chloe Tentchine. She was diagnosed with this disease in March, 2014. Chloe is a singer and is on O2...performing. She has a song 'Be Brave" ( you tube)that she wrote when she came out of the hospital that is very inspirational. The way she handles walking around NY city pulling a fancy 02 cylinder cart behind her could and should be really quite up- lifting for many of us...take a look...you'll like it ...I promise. - See more at: https://www.copdfoundation.org/COPD360social/Community/Questions-and-Answers.aspx?page=0&category=myquestions&sort=lastactive&tags=#sthash.9HzjVcNg.dpuf
