A small number of people have the ability to remember personal events in very strong detail. This condition is known as hyperthymesia.
They can remember many events in their lives, including dates, events, and what they did on certain days. This ability is not just about having an ordinary good memory.
What's interesting is that this ability doesn't always feel fun. Remembering too many events in detail can make past experiences difficult to forget.
It turns out that the extraordinary ability to remember also has another side that is not widely known.
