My oldest son (who much older than you, I'm sure) used to love the original Mcgyver. There was an episode where someone in a lab dropped a test tube and it made them age and die. My child was scared to death to watch McGyver after that. He was about 5 or 6 then.Ever since i watched Despicable Me 2 when i was really little i have been afraid of needles. Also any movie with any type of substance that is ingested, ejected, or soaked up and then changes the appearance or biological structure of a living thing almost makes me hyperventilate. I think thats also where my fear of zombies came from cuz its kind of the same thing.
