What a queasy lot you all are! I have been a cat and dog owner all my life, I don´t let my dog lick my face as a rule, don´t like it, but I´m not saying that he´s not had the odd lick. Dogs are like that. My cat used to jump up on the kitchen counters, cats are naturally inquisitive, he had to have one leg amputated because of cancer and now can´t get up anymore, but I didn´t find it too upsetting, I just put him down every time. Like most people, I use chopping boards for preparing food. Children do eat their snot, whether it upsets you or not, they will eventually stop. I eat snails and love them. There is very little that makes me go "yuck" and I very rarely get ill. My own personal gripe is cloth handkerchiefs, absolutely disgusting, people shaking them out in public and reusing them time and time again. And, as a European, people walking into my living room in their outdoor shoes.
