Of course that's an answer to a very specific question.
I think when it comes to discussions like this people also ask about their own personal circumstances and then the information can appear to be confusing and contradictory.
Fo example if you don't have children, but have surviving parents or siblings, or, if you don't have children or surviving parents and your siblings too have died, but your siblings have surviving children, or perhaps more commonly there are children from other/previous relationships...
