It's Like Being A Newborn, This Sudden Sensory Overload Of Noise, Color, Smells And Gravity After Months Of Quietly Floating, Encased In Relative Calm And Isolation. No Wonder Babies Cry In Protest When They're Born.

Other Anatomical Changes Associated With Long-duration Space Flight Are Definitely Negative: The Immune System Weakens, The Heart Shrinks Because It Doesn't Have To Strain Against Gravity, Eyesight Tends To Degrade, Sometimes Markedly (no One's Exactly Sure Why Yet). The Spine Lengthens As The Little Sacs Of Fluid Between The Vertebrae Expand, And Bone Mass Decreases As The Body Sheds Calcium. Without Gravity, We Don't Need Muscle And Bone Mass To Support Our Own Weight, Which Is What Makes Life In Space So Much Fun But Also So Inherently Bad For The Human Body, Long-term.
