Most have memory loss to varying degrees, but some have strong memories, even well into old age.<p>Rogalski wanted to know just how good.

At the time, researchers thought she was unique. But since then, a handful of such individuals have been identified. And now, researchers are trying to understand how their extraordinary memories work.<p>Bob Petrella, 62, of Los Angeles had to go through a lot of memory testing to qualify as someone with superior autobiographical memory.

Brain Scans Offer Clues Late To Bed, Early To Rise, Makes A Teen Sleepy http://kunc.org/post/late-bed-early-rise-makes-teen-sleepy Most high school students are chronically tired. They juggle school, sports, homework, chores, friends and family.<p>To meet all these demands, surveys show, high school teenagers usually stay up close to midnight on school nights. And then they have to get up early the next morning, typically around 6 or 6:30 a.m., to get to school on time, as most high schools start classes around 7:30 a.m.<p>By Friday, most teens are very tired, says Dr. Helene Emsellem, a sleep researcher with George Washington University.
