Q: How heating can change the water?

A: There's an old saying about cooking a frog.

If you bring a pot of water to boil, then toss a frog in there, that frog will jump right out and run away.

But, if you put the frog in a pot of cold water, place it on the burner and slowly turn up the heat, that frog will sit there, not moving a muscle, even when the water boils, and even as it's getting cooked.

What I'm trying to tell you is that your Grandma died.

I don't know what I was getting at with that whole frog thing.
