"The author suggests that the default or NO ACTION would be a good set up for
life. While I understand that it would be nice if young children didn't lose
their parents, I think it is possible to look at that statement and say that a
parent can't die until he has no children. I believe that no parent should have
to bury their child, so perhaps the author didn't look into the statement
enough."
The best place to *find* answers to programming/development questions, imo, however it's the *worst* place to *ask* questions (if your first question/comment doesn't get any up-rating/response, then u can't ask anymore questions--ridiculously unrealistic), but again, a great reference for *finding* answers.
