Again, based on our patient population, and I also alluded to it in my opening remarks with respect to our need to deploy, we have a limited list capability, which means that we can't take every single drug. We just don't have the capacity to move them. The other thing is that we have stability concerns in our operations. If you take a patch into a cold area compared to a very warm area, the kinetics of the drug, or the absorption of the drug, varies, and therefore we have to take that into account. So there are many factors that we look at.
The other thing is that we have primarily a healthy, younger population, and he has a varied population with pediatrics and geriatrics, which we don't have. So you wouldn't find many of the Alzheimer's drugs on our benefit list. You would not find drugs for some cardiovascular diseases, unless a patient has that condition, when we would do it on a case-by-case basis, as Bruce has said. We also look at the individuals and we tailor the therapy to them. It doesn't mean it's not a regular benefit; it means that not everyone can access it.
