Captain America's Shield. Dr. The shield has great aerodynamic properties: it is able to slice through the air with minimal wind resistance and deflection of path. Its great overall resilience, combined with its natural concentric stiffness, enables it to rebound from objects with minimal loss of angular momentum.
Pneumonia is an infection of the lungs. People with pneumonia often complain about coughing, fever, shaking chills, and shortness of breath. 1  Your body's immune system usually keeps bacteria from infecting your lungs.2  In pneumonia, bacteria reproduce in your lungs, while your body tries to fight off the infection.f you inhale toxic materials, you can injure your lungs and cause chemical pneumonia. Fungus also can cause pneumonia. In certain areas of the United States, specific fungi are well known. Coccidioidomycosis causes a pneumonia called San Joaquin fever or  Valley fever  in the desert regions of California.
There is no simple answer. Pneumonia can be caused by chemicals, viruses and bacteria, by not breathing properly when bedridden, by immune system problems and other causes. The first thing you need to know is the cause of the person's pneumonia. When you know the cause, you can look at treatments. If a normally healthy young person has a pneumonia caused by a bacteria or germ, and if that germ is easily destroyed by ordinary antibiotics, recovery will take a few weeks.
