They're pretty gruesome websites. But on the other hand, they're interesting ways to see people obsessively collect articles about the health conditions/hospital visits of famous people. Basically, you predict 20 people who might die in the next year, and you score points for every person who dies (the younger the person, the more points you score).
It's not really scientific, but it's still an interesting way to develop intuition about what factors ultimately cause someone's death. I've been following these sites for around half a decade now.
