i always think of the 36 foot worm in a jar in the Biology Lab when I was a student. It was taken from the stomach of a 12 year old boy after he ate meat with worm eggs. Every time I was in the lab and we were having a lecture, my eyes always wandered to that shelf and that jar.
I know farmed meat today is very good and farmers worm their animals, but I still could not eat meat that was rare.
