Someone I know got the bad news that he has cancer.
When you hear that, it's final. Before you hear that, it's all "maybe, possibly, who knows?" There's lots of options.
Then you hear it, and you think, Well, this is what I have. Or in this case, what that guy has. But it could be anyone. It could be me someday.
Probably will be someday. You either live to an old age and something kills you or it kills you before you get there.
