Ever walked into a room and completely forgot why you went there?
The investigation
You aren’t losing your memory. It is called The Doorway Effect.
Your brain treats doorways as “Event Boundaries.” Crossing a threshold is like pressing “Save & Close” on a document and opening a new blank one. Your brain archives the old room’s data to free up RAM for the new room.
Pro Tip: This works for studying too. Context matters. If you study while eating gum, eating the same gum during the exam can help your brain “Reload” the information.
