I haven't seen The Hunger Games in theater, yet. I've read the books, though; they're addictive and exhilarating. Everyone diagnosed with a chronic illness is like the tributes. Some of us are like Katniss and Peeta, some are like Rue, and the rest make up the rest of the tributes.
Some are like Rue. These people fight hard. They use whatever skills they have to stay ahead of the game, but in the end they succumb to their disease. They may not die like Rue does (sorry, spoiler alert), but they stop trying to beat their disease and instead let it control them. They start out fighting, looking for ways to make themselves better. They start off like Katniss and Peeta. No book or article goes untouched. But when they can't find a cure, they give up. They accept their "fate" and live in pain and suffering.
And the rest are like the other tributes. They'd like to survive, but they just don't have the same hunger that Katniss and Peeta have, or even Rue. They succumb to the disease pretty quickly. They let things happen to them instead of them taking control of their destiny. They might follow their doctor's advice blindly. They might just say "Well this is how my life is going to be, I might as well get used to it". They give up when they should be digging their heels in and saying "This is not how I want to live my life".
