Question: Does photographic minds exist? What does it do? Do people who have get affected by it? Is it good/bad?

Photographic memory is called Eidetic memory. It seems to decrease as you get older, and I don’t think anyone knows what causes it really – it’s quite rare though! Mostly people who have really good memories, or enter memory competitions use specific strategies to remember a lot of things (like relating a pack of cards to a story, so they can remember the order).
