Will Magic Marker Ink Kill You?

Over the remnants of our dinner plates my son powered into full rant about - "you know what i hate" no what, sayz I, how could i leave him hanging? - "when people tell me how toxic marker ink is AND how bad it is for me  - like I am going to die from it or something."  And then gave a poignant performance of how ridiculous he thought this was.  On one hand he posed the question and the other asked my participation.
