I saw that...... they were absolutely gross!
I am a bit on the queesy side about fingernails. It's quite bizare, I am generally quite robust (went through child birth with no pain relief, twice) but when I break a fingernail... oooo It makes me go all unnecessary. That and drying wet wood, for example a tea towel making contact with a wet wooden spoon .... getting goose bumbs just thinking about it!!
