Why Sitting on the Floor Changes Your Hips, Pelvis, and Spine After 50?

#feynman #humanbody #scienceexplained Why sitting on the floor changes your hips, pelvis, and spine after 50 caught my attention when I realized floor sitting felt completely different from a chair. Through a Feynman-style, science explained approach, I explored floor sitting benefits and how sitting posture influences hip mobility, hips, the hip joint, pelvis, spine, lower back, core, muscles, joints, balance, stability, and movement. I also learned how flexibility, range of motion, rotation, external rotation, internal rotation, hip flexors, glutes, piriformis, adductors, abductors, hamstrings, stretch, healthy aging, mobility, floor, ground, and after 60 movement all work together to shape the way my body feels every time I stand up. 00:00 Intro 03:05 Why Floor Sitting Feels Different After 50 08:30 What Happens to Your Hips, Pelvis, and Spine 13:50 Mobility, Rotation, and Everyday Movement 19:40 Can Floor Sitting Support Healthy Aging?
