United States illusionist and daredevil David Blaine has started another endurance challenge, which consists in hanging upside down for almost three days, above Wollman Rink in Manhattan's Central Park.

The stunt was kicked off Monday morning at 8:30 and is expected to end at 11 p.m. on Wednesday, disregarding doctors’ worries about the damage the stress might cause to Blaine’s internal organs and blood circulation.

”My mouth is dry and I have to go to the bathroom,” Blaine said Monday afternoon. “I feel pressure in my head, and my legs are tingling,” the magician added.

Despite being suspended from a four-storey high metal frame, the illusionist can be lowered in order to speak to fans face to face. He can also free one leg and use its weight to raise his head to a horizontal position.

During the two nights and three days of the challenge, David Blaine will not be eating anything, will be given liquid through a straw and passing water through a catheter. In addition, he won’t be able to sleep at all since he must be awake all the time so as to move his legs and keep the blood flowing.

Dr. Massimo Napolitano said that the risks the stunt involves are really high, the performer actually putting his own life in jeopardy.

"He has a 5 to 10% chance for blindness. He knows the signs - blurred vision, persistent headaches, passing out, seizures. He knows his body better than anyone else,” Napolitano stated.

Blaine’s past stunts include spending 72 hours encased in ice, seven days underwater and 44 days spent without food in a glass box. Nevetheless, he admitted that this one would be the most difficult of all so far.

The reasons behind this daredevil act consist of pushing his own limits and giving himself ”a different perspective, for a short duration,” David Blaine informed. The magician is expected to end his 60-hour challenge at the climax of a live ABC special ”David Blaine: Dive of Death” on Wednesday.
