看AI怎么说：
- "智" (Fluid Intelligence): This is your raw processing power—speed, memory, and quick problem-solving. It usually peaks in your early 20s and then starts a slow, steady decline. This is why younger people are often faster at learning new tech or solving logic puzzles.
- "慧" (Crystallized Wisdom): This is the ability to use accumulated knowledge, social experience, and emotional regulation to make sound judgments. This typically doesn't peak until your 60s or 70s. It relies on pattern recognition over a lifetime of "having been there."
In short, "智" is like the CPU speed of a computer (fastest when new), while "慧" is the size and depth of the database (richest after years of input).
