What Would Kill You First, a Lack of Sleep Or a Lack of Food and Why?

Sleep deprivation adversely affects the brain and cognitive function, and may result in hallucinations and memory lapses or loss.

Recent studies have suggested that sleep deprivation may be linked to heart disease and mental illnesses including psychosis and bipolar disorder.
