David Blaine

Seems idiotic to hang upside down for three days.

US illusionist David Blaine has begun another endurance challenge - hanging upside down for almost three days.

The 35-year-old magician was hoisted by his heels over the Wollmann ice rink in New York on Monday.

He intends to remain there until late Wednesday, despite doctors' concern about the effect of the stress on his internal organs and blood circulation.

Blaine said he was "doing all right" on Monday, though he did admit his head felt like it was "about to explode".

His previous stunts include spending 72 hours encased in ice, seven days underwater and 44 days without food in a glass box.

I'd rather he levitate again.
