I carry hand sanitizer. I don't want to get sick and not be able to go to work. Plus, colds are a nuisance. And sometimes there is no soap in the public restroom.
I'm squeamish. Once I got my finger pricked for a blood test, and the woman squeezed my finger to make the blood come out, and I fainted to the floor. I can't watch gory movies and if I do, the scenes NEVER LEAVE ME. I flash back on them the rest of my life. I remember the first sadistic thing I ever saw in a movie, I was so shocked and hurt, I thought I'd die -- I was about 9 (a man was branded in the chest in the movie). My stomach clenches and I get electric shock feelings in the palms of my hands, and if it's bad enough, I cry and will be depressed for a day or two. Ditto with news having to do with sadists (child torturing, murderers, etc.) Literally makes me sick. It's literally painful in my body. So ... not so much my idea of fun, and since reading about or seeing gore is optional, I opt not to.
I'll rearrange a sandwich if, for example, all the pickles are stacked in one spot, because I don't like the taste of that much pickle at once. I'll eat pretty much whatever you put in front of me, including rabbit or squirrel. I wouldn't eat cat or dog because they're companion animals and it would feel like cannibalism. Although any animal could be a companion animal. Thing is, I don't feel any need whatsoever to be logical in my personal preferences, since they are just that.
