    Ok, that’s normal! I only need 5 hours. I can’t sleep longer. Even if I stay up super late. It’s ALWAYS 5 hours. So glad this video was made. I’ve tried telling people 8 hours isn’t needed for everyone.

    I usually only sleep about 5 hours a day. Can’t stand sleeping any longer. May have something to do with the fact that I have worked the graveyard shift for the past 20 years.

    My mother does this nonsense. Sleeping typically a total of 4 hours.
    I myself am the opposite. & I absolutely LOVE dreaming it helps me realizing things in my day to day life.

    The Russians did a major research project on short sleeper training for its soldiers during the war. Soldiers were trained to achieve rem sleep state in a short time allowing for a 4 hour sleep set as adequate.
