I love your list so much but this made me laugh the most:

3.My mother and most of my aunts are nurses. This led to spending an entire Christmas dinner listening to them discuss phlegm. As a result it takes a lot to squick me when it comes to food.

I had a room mate who was a nurse and I have a younger brother with whom I would compete to 'outgross' when discussing topics so I'm largely immune these days, which used to really distress a very squeamish cousin who couldn't even hear the word 'gag' when eating dinner without feeling sick :)
