“Bob, a TV producer from Los Angeles, remembers every day of his life as if it happened yesterday. His perfect memory is a gift, he says: “I don’t have to mourn people after they’ve passed away because my memory of them is so clear.” The condition was discovered by James McGaugh at the University of California, Irvine, in 2001, after he received a peculiar email from a woman named Jill. “Since I was 11 I have had this unbelievable ability to recall my past,” she said. “When I see a date…I go back to that day and remember where I was, what I was doing, what day it fell on and on and on.””
