You've asked a couple of questions. I'll just make a brief comment about the importance of the caregiving role and the issues there, and then I'll ask Don to talk about that in more detail.
I myself have been a caregiver twice, having lost two of my family members to cancer. I know what the stress is like. In this instance, we're talking about a very, very stressful situation for most of the caregivers. One can say that if you love the person, you'll do everything for them. That isn't enough. The fact is that a number of people who are caregivers have lost their jobs in order to provide the care that is needed. As they age, there is the issue of not being able to provide supports, whether they be physical or psychological, because of the stress.
The caregiving world cannot be underestimated. We were very concerned about what needs to happen in order to strengthen that role and the fact that if an individual hasn't, for example, used VIP, then the opportunity to obtain that is not there. That's really a major concern, and I think Donald would probably like to elaborate on that a bit more.
