I'm floored!
Unfortunately, I've lost two friends within 13 months to lung cancer, both of whom died within 6 months after diagnosis. But they were smokers. It must really, really suck to have lived a good and healthy life, the way Dana had, and still be stricken with an agressive form of this rotten disease.
Poor Will. He was 3 in 1995 when Chris had his horrible accident, so he'll be 14 this year! I hope and am somehow sure, his older half siblings from Chris' first marriage will look out for their little brother.

I think Robin Williams and his family will put in their fair share, too, as they were extremely close to Chris and his family.
It seemed nothing could stop Dana, who - last year - still took part in several events of their foundation. She lost her mother very shortly after Chris died, and now she's gone too. Some people have such a big cross to bear.
