The well-known magician and illusionist David Blaine is jeopardizing his health with his most recent stunt, according to experts’ opinion.

The latest stunt he will impress the public with implies him hanging upside down for a 3-day-period, suspended 50 feet over New York City’s Central Park. Specialists claim the world record holding magician may go blind following the challenge.

You'll feel it," 35-year-old Blaine explains. "The blood gathers in your head. It becomes overwhelming. You start to get a headache. Your eyes start to feel really tight with blood pressure, your legs go numb,” he said. “Your extremities start to tingle. Your lungs feel compressed. And it makes it more difficult to breathe. You'll notice that you won't even be able to talk the same way - your voice will be different," Blaine continued.

Throughout the stunt, he will only drink water. He will not be able neither to eat, nor to sleep and he will make use of a tube in order to go to the bathroom.

According to Dr. Massimo Napolitano of the Hackensack University Medical Center in New Jersey, the consequences of hanging upside down for such a long period of time increases blood pressure in the head, which could cause blindness. Napolitano couldn’t say for how long the sightlessness will persist. The illusionist also faces the risk of swelling and cramps in internal organs, the doctor stated.

David Blaine told the journalists how he prepared for the stunt: losing several pounds, doing out of the ordinary exercises and, of course, dangling upside down.
