How does someone die from pneumonia?
Pneumonia can cause death mainly in senior citizens because it allows for bacteria — and sometimes viruses, but mostly bacteria — to come into the lungs. That will continue to flood the lungs with aspirating material. And you have to understand that as we get older, the immune system is less and less active, and less and less capable of protecting us against these onslaughts of organisms that sit out there and are potentially dangerous for us.
