Me too. I only feel at my best if I'm consistently getting 8 hours. A few days of 7 hours and I start to feel overly tired. Turn that down to 6 hours and I turn into an awful person.

My wife hardly ever sleeps more that 6-6.5 hours so she basically gets 2 extra hours a day compared to me. This has been true for me as long as I can remember (36 year old male)

Is there any difference in your level of fitness? I need a lot of sleep as well.

The more physically active/fit you are the longer you have to sleep.
