I do always keep my kitty indoors. He has killed a few mice, who got in the house last year. I wasn't very happy about that even, as I was trying to catch them and get them outside.
I grew up sneezing into my elbow on account of learning to cook at a young age and growing up cooking. You can't always take your hands off what you are doing in order to sneeze into them and then wash them. I always turn away from whatever I am doing too, or away from whoever might be there in the line of fire. Though most of my sneezing while cooking is induced by pepper, not a cold.
I don't go through electronics at the rate some do. I still have a very outdated cell phone, a twenty year old telephone, a fifty year old telephone (which just stopped working. Probably needs re-wiring, which I intend to do one of these days), TV, VCR, DVD player, and stereos that are over ten years old. I gave away the ones I had before I got these, when I moved house. My brother got my last desk top to salvage things from it before he turned the rest in for recycling. He lives in San Francisco and that city has some of the strictest rules about waste now that I have ever seen. You pretty much have no choice but to recycle everything they demand you recycle, or they won't take your trash.
If I ever did get pregnant I would certainly donate my placenta. I'd donate my eggs for stem cell research too, if they would take them.
The smiling is an odd thing. I don't consciously smile. I get tons of people smiling at me, which sometimes startles me, and I figure I was either unconsciously smiling while daydreaming, because I kind of zone out when in crowded places due to a fear of crowds that I have mostly, but not completely, overcome, or the expression on my face when the sun is in my eyes looks like a smile. I remember once in high school, which I hated, some kid said to me "Why are you always smiling? There's nothing to be happy about!" and I was like "WTH? I wasn't smiling. I never smile. I hate it here!"
