People participate in a singing class at Royal Brompton Hospital in London, Monday, June 17, 2013. The weekly group is led by a professional musician and is offered to people with respiratory problems including asthma, emphysema, and Chronic Obstructive Pulmonary Disorder, or COPD. Doctors at London's Royal Brompton Hospital started the program after reasoning that the kind of breathing used by singers might also help lung patients. (AP Photo/Sang Tan)
