Who knew?

I'm thinking of my sister Kelly - could she have warded off cancer?
Had she known of the wands 3 or more years ago, and practiced holding them 2 hours a day....
Would she have done that? Not likely.
We don't get to to play the what-if game, just as we don't get to "know."
If, then - if only this, then that!
Maybe the wands would have done nothing for Niko... we just don't get to know. -_-
And you know I hate not knowing.
