Well... I have a bad knee!

This is just another interesting TED post.  I suffered a knee injury when I was 19 and was promised a 100% recovery after the reconstructive surgery.  I still today, 5 years later have trouble using the leg at all.  This is medical field based, however I still find interest in the technological advancements that shape our lives today.  This idea of bio medics is such a strange but good example how humans have the ability to completely morph nature to our needs.  Im not sure how I feel about it but it would be nice to run again.
