The muscles used in breathing, such as the diaphragm, do weaken. The number of air sacs (alveoli) and capillaries in the lungs decreases. Slightly less oxygen is absorbed from air breathed in. The lungs become less elastic. In people who do not smoke or have a lung disorder, these changes do not affect ordinary daily activities, but these changes make exercising more difficult.
The lungs become less able to fight infection, partly because the cells that sweep debris containing microorganisms out of the airways are less able to do so. A cough, which also helps clear the lungs, slowly becomes weaker. Lung contractions decrease in intensity (size).
A major increasing problem is air pollution with an increase is small size particles in the air. These dust and other particles have a damaging effect on the lungs and in many cases more than smoking. But when people combine the polluting efforts it is eminent that they enter a danger zone.
Lungs should be trained in a not so usual suggested way. Singing is a great way to train the lungs. Joining a group is the best way to receive training and get social connections. A quire or a choir is a group of singers that practices and performs together. The best place is one which pays attention to the physical training behind the singing.
