When are you going to die?

I have a 3 year old that is really trying to understand life after death.  This was her question for me this morning.

Miss Reina, when are you going to die?
When I'm old, I reply.
No, where will you go when you die?
I don't know, I've never died before, I say.
No, where will you go when you die?  she asks again, not happy with my answer.
I don't know.  If I've died before, I don't remember.

Frustrated, she tries a different tack.

Where's your God? she asks.
In heaven, I say.  I'm not sure if I believe this, but I know she does, so she is happy, and lets the matter go.  I think she just wants to make sure I'm going to be ok when I die.  She's looking out for me.

Wouldn't she really flip out if she knew that everyone asks this question at many stages of their lives with varying degrees of certainty.  She wants answers, and adults are supposed to know them!
