How does a man in his 70s, who used to need only a primary care doctor and a dermatologist, end up needing many specialists?

As people age, their bodies go through various changes that can lead to multiple health issues. For a man in his 70s, even if he was relatively healthy a few years ago, age-related conditions like osteoporosis, heart problems, and others can start to appear. These issues often require specialized care. Additionally, older adults are more prone to falls and injuries, which can lead to seeing orthopedists, neurologists, and other specialists. The increase in specialist visits can also be influenced by having good health insurance and access to medical resources. It's common for older adults to see multiple specialists to manage different aspects of their health.
