Rushed to a Massachusetts emergency room four years ago, 28-year-old Jacob Haendel exhibited signs of stroke. Doctors thought Haendel was in a vegetative state and would soon die, but the one-time chef was very much awake and conscious, suffering from locked-in syndrome – a purgatory between life and death. Correspondent Lee Cowan talks with Haendel about his extraordinarily rare medical trauma, and about his remarkable recovery.
