Developers often struggle to revisit their own code, not due to poor logic but because of Cognitive Budget limits. Human working memory handles only about five to seven items at once. Exceeding this leads to dropped context and missed bugs, highlighting a need to code for human limits, not just machine capabilities.

The common trap is the "Kitchen Sink" function, which crams loops, date calculations, and null checks into one monolithic block. This forces a developer to track multiple variables and complex state simultaneously. When interrupted, the entire mental stack collapses, making the code fragile and difficult to debug or extend.

The solution involves Quarantining Complexity into smaller, named functions. By breaking logic into concepts—like separating a filter predicate from the main data flow—developers reduce mental load. This declarative approach, using methods like `filter` and `map`, clarifies intent over implementation, making code boringly obvious and easier to maintain.
