Not getting enough sleep? Maybe you don’t need it.

Scientists have discovered that DNA determines how much sleep we require. Researchers at Ludwig Maximilians University Munich found hat people with a variant of a gene known as ABCC9 can function well on a lot less sleep.

How about the rich and famous? According to Family Circle magazine:

Madonna can get by with 4 hours of sleep
Margaret Thatcher is also good with 4
Heidi Klum 10 hours! Come on, that poor girl works 23 hours a day
Mariah Carey is also a 10 hour girl
George Clooney is good with 6 hours

How many hours do you get?
