While doing some slicing and dicing in the kitchen with a Wusthof santuko (very sharp, yikes) I noticed that I had somehow gouged the over mold of my Fuelband with slightly errant cutting motion. See the attached photos. Without the Fuelband on I would have likely taken that gouge out of my wrist and probably would have bled to death right there in the middle of my kitchen. Thanks Fuelband for saving my life!
Lesson: don't leave home without your Fuelband. I am pretty sure Scott B also has a story of his Fuelband saving his life.
