Cyborg Edition! This one is courtesy of Mrs. Hatrack who dreams regularly of becoming a cyborg. What parts of yourself would you replace with crazy mechanical goodness?
Being ever so practical, Mrs. H wants new knees (but not the recovery/rehab necessary after) and more importantly a new spine to replace the one that is slowly disintegrating away. I think I'll go with eyes. Not just to get rid of the glasses I've worn for over 35 years but new, improved super eyes. Long distance vision, microscopic vision, adjustment settings for bright and low light... I could do without the creepy red glowy thing my friend in the gif has going on, though.
