Okay, well, I'll give you that fact also, then. This is of concern to us.
The other thing both of you have mentioned is repeated application of this causing some concern. I'd like to hear more about this, because again, this is allowed right now, and we are aware that there are different evolutions of this device that will come that will have even higher applications in a timeline.
Could you, first of all, talk about why you have the concern about more than one application, even though it is allowed?
