The cyborg arm wasn't all it was cracked up to be. It had seemed fine, at first--good and stronger than her injured arm was. The pain in her joints had gone away. The interface didn't look very good--but she'd just looked away. It didn't keep her from getting laid; novelty could do wonders for a girl's prospects in that department.

She would eventually have to get an old-fashioned hip replacement anyway. Why not skip ahead and get the better model? She'd saved enough to replace the hip--
