Bangalore: “Each night, when I go to sleep, I die. And the next morning, when I wake up, I am reborn,” is a very popular quote by Mahatma Gandhi. Sleep is vital in all our lives and it would be impossible to get our daily routine going without sufficient sleep. Researchers also claim that an average man must have at least eight hours of sleep every day, for the body to function normally. But for few people less sleep does not matter, a study proves that one to three percent of the world populations are among the ‘sleepless elite’ (who can survive happily with just few hours of sleep).  Below is a list of great and successful humans who may or may not fall under the elite group, but have achieved great heights with minimal sleep, as compiled by Business Insider.
