    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.

Mythology expert and Professor of classics Peter Meineck deep dives into all 48 of the constellations the ancient Greeks used in the night sky. From maritime navigation to agriculture and timekeeping, Meineck explains how eight main groupings of constellations were tracked in the night sky—and how they translate to today’s mythological storytelling.

What do Iron Man and Odysseus have in common? The book traces Marvel’s intricate universe back to its earliest mythological roots. Meineck uses beloved heroes like Spider-Man and antiheroes like Deadpool to demonstrate how ancient themes persist in today’s pop culture. He draws compelling parallels, connecting Black Panther to the legend of Atlantis and revealing how disabled heroes like Daredevil have archetypes dating back to Hercules. The book explores the shared struggles of characters like Scarlet Witch and the sorceress Medea, showing how these timeless narratives have shifted to reflect society’s changing values.
