BBC NEWS | Entertainment | Blaine counts down final hours: "The countdown to freedom has begun for the illusionist David Blaine, who is due to leave his Perspex box on Sunday night.
Tens of thousands of spectators are expected to watch the 30-year-old American be lowered to the ground, placed on a stretcher and rushed to a private hospital.
He has apparently spent the last 43 days in the box, which is suspended next to London's Tower Bridge, surviving on nothing but water.
A nutritional expert has warned that Blaine risks sudden death if extreme care is not taken when he begins eating again.
Professor Marinof Elia, from University of Southampton, said the illusionist could be at risk from serious problems including sudden death.
The magician has described suffering severe heart palpitations, blurred vision and breathing difficulties as his fast neared its end. "
