As he put the bags full of...he chuckled. The bags were full of nothing but lettuce. Of course they were. Mom was shopping for a donkey. His back suddenly started feeling stiff. Almost like there was a steel rod in it. He took a step, and groaned. He felt unsteady on two legs all of a sudden. He looked outside to his mother and sister on their hands and knees. Wait...oh no...back pain...
"Crap it's affecting me!" He exclaimed and headed towards the chronivac. Every step hurt. His body was screaming at him to go to his hands and knees, that it wasn't proper to be on two legs. He started to hunch over. To his shock relief flooded him the more he hunched. He put his hands out in front of him, and before he knew it they were resting on the kitchen tile...and he on his knees. It felt...wonderful. The pain in his back was completely gone.
