I wonder how many students have this same affliction. I'm currently studying hematology and immunology and now I visualize those white blood cells attacking the foreign bodies.....from the 1966 movie "Fantastic Voyage". I now realize that at about age 11 I had already travelled through the heart, past valves and faced those killer white blood cells.
I got my first medical training for 5 cents a day, to see 20-minute segments of movies in an auditorium during lunch break. The visuals while I try to study can be a bit distracting!
