I'll condition my statements on not being an expert in health human resources, but I know that there are opportunities to change the mix of trained professionals providing health care. However, at the same time, a lot of the costs being driven by the aging baby boomers, for example, are driven by the increasing intensity of the health care services provided. For example, we have new and innovative diagnostic techniques, new and expensive therapies, and also devices. These are increasing the costs as well as the aging of the population, so I think we have to view it in the frame of several different cost drivers there.
