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.
