However,some people are not that lucky.A middle-aged man came out of a park in Seattle, in the U.S.,stopped a passing car,and said to the driver."I don't know who I am,and what city I am in." He had no ID and was carrying $600 in his sock. A local newspaper published his photo in print and online,and an English teacher in Shanghai identified him as Edward Lighthearted. Letters came in from different parts of the world confirming that Dr.Lightheart was in fact an international pubic relations consultant. But the world traveler,who spoke four languages,had no idea how he had achieved those skills. He remembered being married to a woman in Europe named Tina,who had died,and he wore her ring and his on his finger. Doctors said he was suffering from disassociated amnesia: he could remember loose bits of information. He was able to connect with his sister,but his memory of many events in his past was more or less lost.
