As people age they can lose their ability to maintain their balance. A new approach to dealing with this problem was reported in The New York Times. This new system uses randomly transmitted vibrations to the soles of the person's feet. While the person could not consciously feel the vibrations, the person's body could and it would adjust their balance to the point that 75 year olds were responding like 25 year olds. It shouldn't be too long before inserts are available to put in your shoes. This is the ultimate tie-in to the song Good Vibrations.
