Silly question! What is your gross out kryptonite?

My grandma and aunt were nurses who dealt with all manner of gross things bodies do and soldiered on in ways more squeamish people would not dream of…but they had their little things that got to them. They said this is true of all nurses. “We all have our kryptonite.”

Grandma got grossed out into gagging by compound fractures.

Aunt felt sick whenever dealing with maggots in wounds.

What are your “ewww” things?
