How come David is always so full of energy?
He has a strange but highly effective way of sleeping.
What is that?
He takes a short sleep for an hour every six hours and has a total of four hours of sleep each day.
Where did he get that strange idea?
He read flora a book which said it was the best way for human beings, and he believed it.
How many hours do you sleep a day?
I need at least seven hours. I once tried to follow David's example, but it never worked out for me.
If I sleep during the day, I can never wake up.
Not everyone is a David I guess.
