Keith Richards has a warning for illusionist David Blaine ahead of his sleep-deprivation stunt - the rocker ended up with a broken nose when he stayed awake for nine days. Blaine plans to go a record-breaking 13 days without sleep later this year.

Rolling Stone Richards claims he managed to stay awake for nine days back in the 1970s, thanks to a cocktail of narcotics - but the feat ended badly.

He reveals, "On the ninth day I was putting a tape into a tape deck. In 0.3 of a second I fell asleep and crashed head-first into a JVC speaker, smashing my nose apart. I just lay there and let it bleed. It was a chemical thing."
