The uncontrollable risk factor that puts individuals at more risk for contracting a disease is **age**. As people get older, their immune systems may weaken, making them more vulnerable to various illnesses. Age is a significant factor in determining the body's ability to fight off infections and diseases.
For example, elderly individuals are more likely to suffer severe complications from diseases such as the flu or pneumonia compared to younger individuals. This is due to the natural aging process that affects the immune system's response to pathogens.
In contrast, factors like diet, physical fitness, and personal hygiene are considered controllable risk factors because individuals have the ability to make choices that can positively impact these aspects of their health. Age, however, is a factor that cannot be altered or controlled.
Therefore, when considering the risk factors for contracting a disease, age stands out as an uncontrollable element that plays a crucial role in determining an individual's susceptibility to various health issues.
