Am not watching, but oh my GOD. This is stuff from my childhood nightmares.
I remember when I was a kid, I came across this show on the Discovery Channel that was about parasites. I still remember that guy who went fishing with his friends and ate an undercooked fish. When he defecated, there were hundreds of tiny worms in his feces. Or the woman who was losing weight uncontrollably, only to discover that she had a 30 foot tapeworm inside of her. ffff
That mess scarred me for life. I still can't eat sushi.
