You’re supposed to learn how to disconnect your brain from your stomach in junior high school, when the boys at your lunch-room table try to geek you out with disgusting tales and upsetting images.
If you can survive such psychological conditioning, then you can go on to become surgeons, military officers, and commanders of minions.
If you can’t, you will be chased from public life by a worm.
What worm? AAAAAAAAHHHHH!!!!
Actually, that continued well into my fifties when the guys in my kung fu school would try to gross me out when we'd all eat at an authentic Chinese restaurant. I was vegetarian at the time and was delighted to have sea cucumber. They told me that juvenile sea cucumbers could extrude their stomachs. Mmmmmmpff.
I had teenage brothers when I was in grade school so that by the time I got to junior high, I could gross out the boys. Yah. Like that.
