The Media add a lot to these stories and then rumors start flying around. I am sure they are really meant to be placed in like Sex Offenders, Terrorists etc. They might even put them into the elderly or maybe even military. Thus the medical uses. Also they were probably talking about the right hand for the Terrorists and middle east cause they wipe there ass with the left and the they cut there left hands off when the do really bad things. Leads me to believe it's meant for criminals.
They just take the true story and muck it up so you'll read and it gets passed around like now. We just got spammed. Solution stop reading or watching the news and see how much happier you are.
