Did you know that there is a rare condition called hyperthymesia that allows people to recall almost every single detail of their life? That’s right… every conversation, every date, every interaction… ingrained in their memory forever. Right now, there are an estimated 12-60 people in the entire world who have this condition and are able to remember each day of their lives.

People with hyperthymesia can think back to any date and remember what they did that day, what the weather was like, and even what they ate. Many of these people can mentally visualize these events, as well. While some people might think it would be awesome to be able to remember every detail of their life, many who have hyperthymesia find that it interrupts their day-to-day activities and relationships with others.

This condition is depicted in the television show Unforgettable, which aired on CBS and A&E from 2011 through 2016. The series centers on a police detective who has hyperthymesia and uses it to help solve cases. Can you imagine remembering every single detail of your life—even the ones you want to forget?!
