"Memory is fascinating. Take this psychological experiment... A group of people were shown 10 various childhood images, nine were really from their childhood and one was fake: their portrait was pasted into a fairground they never visited. Eight percent recognized themselves... They recognized the fake photo as real! Twenty percent couldn't remember. The researchers asked them again. The second time, the others said that they remembered the image "Such a wonderful day at the park with my parents." They remembered a completely fabricated experience. Memory is dynamic. It's alive. If some details are missing, memory fills the holes with things that never happened."
