What 90 Seconds of "Overhead Reaching" Does to YOUR Posture After 60

Discover why lifting your arms overhead gets harder after 60 - and why it has nothing to do with a stiff shoulder. This video breaks down thoracic spine degeneration, somatosensory cortex remapping, and proprioceptive fall risk. Learn why your brain is quietly "erasing" part of its own body map, and find out the four-system chain reaction happening every time you reach for a high shelf without you knowing. Whether you're curious about what's really happening inside your aging body, looking for explanations that actually make sense, or someone who wants real neuroscience instead of generic stretching advice, this will change how you understand your own spine. Watch now to discover what nobody tells you about the movement your body is slowly forgetting.
