I had read, but not really understood, the extent to which pregnancy is really disgusting. And sort of painful (mostly back pain, a little leg pain)...but mostly disgusting. When it's not beautiful and life-enhancing, that is. If you ever want to really, really understand what your digestive system is, and what it does at every stage of food processing, and if you, further, want to understand all the things that can go wrong with that system, then become pregnant. I'd give you examples, but the very act of giving those examples might inspire in you some of the same symptoms, if you're eating at the time of reading, or if you have recently eaten. And I'd rather you find out for yourself, if you're so inclined. It's like I imagine the pain of childbirth will turn out to be, which is to say much worse than anyone will ever say, because they don't want to scare everybody off, thus dooming the human race.
*Photo note: of course, this Danish sign reads 'bath and toilet', but I prefer to ignore the + sign, and read it in English.*
