When is enough enough  

I think sleep depends on person to person, one person can survive on five hours asleep and still be fully functional throughout the day and not get tired, others need 9 sometimes 10, I think 8 hours is just an average and not everyone can live on 8 hours. For me 8 hours is not enough, I like my sleep, trouble is I could easily sleep 10, 11, 12 hours! What I do find lately is that when I do get up I feel that I haven't slept at all and I just want to turn over and sleep more even though I've slept for 8 hours. I could never last on 5 hours I would be a walking zombie!

Well, I've know a few people who would sleep for about 12 hours a day. and get up and be very active till it was time for the to start their routing over again. But, I had one friend who was suffering from severe depression, which started to make me questions whether or not he was still alive. I use to see him close to everyday till his depression got worse from him losing his job. Then one week he was sleeping for 12hours a day, then the next week it would be 18 hours a day, and after it got to the point that the only time he would get up from sleeping would be to eat and use the restroom. He seemed to be sleeping close to 22 to 23 hours a day, and he did this for about three months till he got his doctor to put him on some medicine. I don't know how he was able to stay awake long enough to schedule an appointment to see his doctor, but I can only imaging what life was like for him during those three months.
