Which disease affects individuals of all ages, including athletes?

Arthritis is a condition that can indeed affect individuals of all ages, including athletes. It encompasses a variety of conditions that result in inflammation of one or more joints, leading to pain and stiffness. This means that both young athletes and older individuals can be diagnosed with various forms of arthritis, such as juvenile arthritis in children or osteoarthritis in older adults, which is often linked to wear and tear on the joints.

The nature of physical activity, especially high-impact sports, can also lead to joint stress and potential injuries that may develop into arthritic conditions over time. Consequently, athletes are not immune to experiencing joint inflammation or arthritis, as these issues are related to both genetic predisposition and lifestyle factors.

Other conditions listed, such as osteoporosis, heart attacks, and Alzheimer's disease, typically have age-related risk factors or patterns. Osteoporosis primarily affects older adults, heart attacks are more common as one ages and has lifestyle factors, and Alzheimer's is generally associated with older populations, making arthritis the most inclusive of the listed diseases in terms of age range.
