Age is a classic intensive level quantity—an absolute property of each entity at a point in time. The range [21, 40] is bounded and centered away from both 0 and 1, consistent with a physical level. Summing ages across boxers is meaningless; averaging (mean age of a group) is the natural rollup. High confidence intensive_additive. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
