    YET………………….Peoples sleep habits have nothing to do with genes
    and everything to do with WORK and Lifestyle if you work night shift you
    sleep in the day and sleep most of the day. if u have no job and party all
    night u sleep all day if your responsible and go to work every day at 7:00
    AM u go to sleep early. I hope every one involved with this study gets

    If I wake up early I go to bed early. If I wake up late I go to bed late.

  6. Hassan Sahl says:

    I tend to sleep at normal bed time but when I wake up at 6 a.m I feel
    anything but fresh. So,is sleep duration something that has to do with age?
    When I was a kid, I woke up really early but not anymore :(

  7. Jordon Franks says:

    6 hours of sleep has zero effect on my drowsiness, neither does coffee

  11. Mutant Baby says:

    Then how do you explain cats? They all sleep and get up at random times.

  12. Steven Wang says:

    How is the circadian rhythm genetic? It has to be trained by the
    environment; the environment is what defines times like 12:30 – so it
    stands to reason that your biological clock can be trained by adjusting
    environmental indicators.
    But sure, teach people that it’s not their fault.

    I can’t sleep at night cuz I’m always on Youtube

    So should i change professions

  15. uroppafollowsme says:

    I “fixed” my biological clock to let me sleep and wake up earlier, but I
    never woke up feeling refreshed. Now that Im out of school my body is
    slowly creeping back into late-sleeper territory and the transition isn’t
    easy. I’m sleeping 12 hours straight each day and my body isn’t giving me
    any indication that it’s time to wake up. Actually think I might just have
    hypersomnia. Because even when I could go to bed and wake up early, I had
    to take naps throughout the day, so my total sleep time was usually around
    12 hours anyway. Lol

    I am ( by the time you read this it might be “was” for the grammar police
    of YouTube )watching this video at 2:09 in the morning, freaking out and
    trying to sleep.

    weekends 🙂 Never tired at night though. I wonder why :)

  18. sandy89107 says:

    I want to know why I am wide awake at 2am and tired as hell at 530 when it
    is time to get up? sleeping pills only work for 4-5 hrs (all of them)
