A child's prediction

I just remembered a thought I had when I was a little girl.  I think I was in the fourth or fifth grade, and both of my grandfathers had already died from different cancers.  My aunt was battling cancer, as well. 
I remember noticing one day that both my grandfathers had blue eyes.  My aunt also had blue eyes.  I had blue eyes.  No one else in our family had blue eyes...that I could think of.  I remember really investigating this, I think it was a holiday dinner at grandmas, where everyone, all my cousins and aunts and uncles were.  I remember looking at everyone.  Checking out their eyes.


It sounds funny, but I was serious.  I can't believe I forgot all about this.  I was convinced there was a link between cancer and blue eyes.  I also was convinced I was going to get cancer, because it ran in my family (those who had blue eyes).
