For most of us, our memories are filled with the minutiae of our personal lives. We tend to remember that relatively unimportant time we went to McDonald’s with our grandma for years, while information learned in high school about the U.S. Constitution slips away just months (if we’re being optimistic) after learning it. For people with highly superior autobiographical memory (HSAM), it’s even more dramatic.
People with hyperthymesia, as it’s often called, can remember almost every little thing that happened to them over the course of their lives. They can remember back to things that happened to them in the crib, and can often recall in great detail every single event they’ve experienced, no matter how minor, from the point when they were 10 or 11 years old. They can remember that the U.S. invaded Iraq on a Wednesday in March 2003. They can probably remember what they had for breakfast that day, too, and whether or not they felt tired. Here are nine things you might not know about the rare condition.
