Hello,

Yes, very interresting links. But the bit about everyone needing 8 hours sleep has been found to be a belief. There are naturally short sleepers, long sleepers, and, of course, average sleepers. If you sleep 4 hours a night and feel that you are in your usual condition 'fit and alert' then there is no need to force yourself to get more or for the person who shares your life to worry. Of course I am talking about persons without neurological disorders.
