Older people are NOT increasingly susceptible to

A) pneumonia.
B) Parkinson's disease.
C) common cold viruses.
D) dementia.

While older people may be more likely to develop complications from viruses such as the common cold, they are not necessarily more susceptible to contracting them. Research shows that the immune system in older adults can still mount a response to fight off infections. Additionally, research has shown that older adults may be less likely to contract cold viruses due to prior exposure and the development of immunity over time. Therefore, pneumonia, Parkinson's disease, and dementia may be more common in older adults, but susceptibility to common cold viruses is not necessarily increased.
