     American magician David Blaine left the glass box in which he had lived for 44 days without food on

October 19, 2003. Hundreds of people came to watch the end of his starvation experiment, which has

become one of London's main tourist attractions.

     Looking thinner and darker, 30 year-old Blaine was taken out of his box over the River Thames and

immediately went to hospital. He was then slowly reintroduced to food, a process doctors say could be

life threatening. He had been drinking only water since September 5.

     A native of Brooklyn, New York, Blaine first became known as a street magician in the early 1990s.

He soon found himself doing magic tricks in bars for the likes of American actor Leonardo DiCaprio and

his super model friends.

tricks aimed at getting a lot of attentionIn 1999, he was buried in a coffin (棺材) for one week and, in 2000,

he spent 62 hours in a giant block of ice. Last year he stood on top of a 25-meter pillar (柱子) in the center

of New York for 35 hours before jumping into a pile of boxes.

     "I think a lot of people are unable to accept that they're able to do what they can do," he said. "They

don't realize we can survive. The human being is an amazing creation."

     But he seems to have suffered from spending so long in the glass box. He said that at times he was

unable to see, had serious back pains and lost his sense of taste.
