The elderly have a less effective mucociliary escalator, as well as changes in their immune system. This causes this age group to be more at risk for the development of pneumonia
In 2011, it was estimated that respiratory tract infections were responsible for approximately 3 million deaths worldwide. These infections include pneumonia, influenza, and other respiratory illnesses. The burden of respiratory infections disproportionately affects young children, the elderly, and individuals with pre-existing health conditions. Efforts to improve vaccination and access to healthcare have been ongoing to reduce these fatalities.
This is such a complex questions and medications in the elderly can cause respiratory problems and sometimes is not classified under geriatrics. Please go on the link below. http://www.chestjournal.org/cgi/content/full/115/suppl_2/158S

Cold air from an air conditioner itself does not directly cause pneumonia; however, it can contribute to conditions that increase the risk. For the elderly, exposure to cold air may lead to respiratory issues, especially if they have underlying health problems or weakened immune systems. Additionally, air conditioning can dry out mucous membranes, making it easier for infections to take hold. It's important for elderly individuals to maintain a comfortable temperature and humidity level to support their respiratory health.
12 to 18 breaths per minute
Small particles, such as those found in air pollution or allergens, can penetrate deep into the respiratory system when inhaled. They may cause inflammation, exacerbate asthma symptoms, and lead to respiratory infections. Over time, prolonged exposure can impair lung function and increase the risk of chronic respiratory diseases. Vulnerable populations, such as children and the elderly, are especially at risk.
Graybeard coughs and wheezes in the book "Boy in the Painted Cave" because he is old and likely suffers from respiratory issues such as asthma or bronchitis. These health problems are common in elderly people and can cause difficulty with breathing and chest congestion, resulting in coughing and wheezing.
Open wounds and poor sanitary conditions.
Elderly individuals often have weakened immune systems due to aging, making them more susceptible to infections. They may have a history of frequent antibiotic use, which can lead to the development of antibiotic-resistant strains of bacteria. Additionally, elderly individuals may reside in long-term care facilities where there is a higher prevalence of resistant bacteria.
Elderly individuals are particularly susceptible to various bacterial infections, including pneumonia, urinary tract infections (UTIs), and skin infections such as cellulitis. Pneumonia, often caused by Streptococcus pneumoniae, can be severe in older adults due to weakened immune systems. UTIs, commonly caused by Escherichia coli, can also lead to complications if not treated promptly. Additionally, elderly patients may experience infections from antibiotic-resistant bacteria, making prevention and prompt treatment essential.
