Sleep and Brains

I

I was watcing T.V. this morning .A medical panel was on the show . They were discussing this and that . The topic of evolved human brains came up . A scientific study showed that women's brains were much more evolved than mens . That women were actually much smarter than men, on a general whole . Since women were so much smarter and their brains more evolved than mens brains, they were able to muti task much more than the average man . The study went on to say that a person who has a more devoloped brain would require more sleep then the normal persons typical 8 hours . So , I am thinking I must have a SUPER devoloped brain . I need at LEAST  8 hours sleep , sometimes more to be a cordial  person , lol !How many hours of sleep do you need?
