Are you among the ‘sleepless elite’?

Did you know Shah Rukh Khan can get by with just four hours of sleep? And that's certainly not because he's an insomniac. Khan belongs to what scientists have identified a small group of people called the 'sleepless elite,' for whom a lie-in is a waste of time.

Rather than being tired, bad-tempered under-achievers, the 'sleepless elite' are an energetic, outgoing and optimistic group who can happily and healthily get by on just four or five hours of shut-eye a night.

They also tend to be slim, able to hold down two jobs at the same time, and breeze through their extra-long days without needing caffeine pick-me-ups or catnaps.

American scientists who studied an extended family in California focused on a mother and daughter who appeared perfectly healthy despite their shared lifelong habit of getting up early in the morning, having gone to bed close to midnight.
