Jill Price remembers everything.

Not just the big moments—everyday details, dates, what she wore, what she ate, and what was on TV decades ago. Born in 1965, he’s one of the first known people diagnosed with hyperthymesia, or Highly Superior 

Autobiographical Memory (HSAM).

When researchers tested her, they found she could recall random dates from her past with uncanny precision. Her memories weren’t photographic, but emotional and deeply personal—like flipping through a mental diary that never fades.

It sounds like a superpower. But Jill described it as exhausting. She couldn’t choose what to remember—or forget. Even painful memories stayed sharp and ever-present.

Scientists are still uncovering how this works. Some believe it’s linked to differences in brain regions tied to emotion and memory storage. Others think obsessive habits may help reinforce those memories.

Whatever the cause, Jill’s story reshaped how we think about memory—not as a perfect record, but as something built, shaped, and sometimes unshakable.
