An advocate is defined as, "One that supports or promotes the interests of another." Given this definition, as a family caregiver, you are the ultimate health advocate, because you are constantly supporting the health interests of your loved one.
It's important to do an annual review of your family's insurance plan. Most people take less time choosing their plan than they do watching a movie. A little extra time every year to make sure you have the best plan to meet your family's needs can save you thousands of dollars down the road.
