On Tuesday we heard from a couple of doctors. One of them was very adamant that it was not a life-threatening shortage, and the other doctor said it's very difficult to measure how threatening or how serious the shortage was. In fact, this morning I was speaking with a doctor who runs a clinic that offers the services, and he was telling me that within the chain of service that the patient receives, this comes at a later level, and there are many alternatives and possibilities that the patient can receive—first, a stress test, and perhaps many other instruments to diagnose a patient. So I would like you to respond to that.
There are a lot of reports that, in terms of these instruments, we could have had alternatives, even different tools, or the fact that isotopes could have been provided from somewhere else. Could you respond to that, please?
