How this receipt has changed
Physical exercise stimulates the body to release proteins and chemicals that improve the structure and function of the brain.
This receipt has not been rewritten since it was published on 04 Oct 2026. Its current version is 1.
Weight is the one the receipt's balance bar uses: every source counts 1, plus a bounded bonus for how often it has been cited, so one famous paper cannot outweigh three dissenting ones (at most 3x a bare source). It is a reading aid built from facts the receipt already stores, not the engine's confidence.
