Blood crosses. They happen when siblings, or cousins, or some other kind of relatives have children together. It's something that disturbs me a bit. I suppose you could fall in love with a relative, but it's a bit frightening what things could happen as a result of such a relationship.
I heard mention of it in the book called The Story of Edgar Sawtelle, by David Wroblewski. The Sawtelles, the family upon which the book focuses, keep careful records of every dog they have bred so that no dog will have a blood cross. Blood crosses have sometimes resulted in physical defects, both in animals and in people.
I was reading National Geographic not that long ago (it is one of my favorite magazines, after all, and I renew my subscription every time it runs out) and apparently it seems that King Tut may have been the result of crossed blood...And that could be why he is pictured with a cane (had some sort of foot problem from the blood cross, perhaps? And maybe he had a weak immune system, too, which would have contributed to his death at such a young age). Among royalty it isn't uncommon to have blood crosses. Sometimes it's to preserve political power (which confuses me a little, because if you wanted to be more powerful, wouldn't it be better to marry someone out of your family so you would have more connections? But oh well) and other times people do fall in love with their family members.
There was also a guy who was French royalty who had crossed blood flowing in him and he developed slowly (I think he couldn't walk until 7? Or something freaky like that) and he didn't live that long. Isn't that painful? The odds are against you from birth. If you're the child of two relatives, then there's a possibility that both of them have a recessive gene that could cause problems, and if you happened to be unlucky enough, you might be born with those two recessive genes put together, and you would suffer from whatever problem the gene causes. And you'd be doomed to get cancer over and over again or die early, and so on. (Hmm, I suppose you could end up with such genes even if you didn't have crossed blood, but in that case you'd have to have two people meet who had some sort of similarities in genes, and I guess considering the amount of people out there it would happen, but then again there are a lot of combinations of genes that are possible, too...Well, never mind me, just talking to myself. Really. No one reads this besides my future self anyways.) I guess in that case you might not be able to change your fate. But I've heard this quote that "It's not the years in your life, it's the life in your years", so even if you know you don't have long to live, search for happiness. You're alive, so go and live as much as you can! That's still something I need to do.
I've been concerned about bloodlines because of my grandparents on my mother's side. People in China don't necessarily change their last names when they get married. In the case of my grandma, she already had the same last name as my grandpa, so there was no need to change last names. True, there are a lot of people in China, and you'll certainly meet people with the same last name, but it made me think that there's probably a blood cross, even if it's somewhere way back. A bit freaky to think about. One time I said to my mom, "So that's why you're so twisted!" (referring to her personality) which made her become indignant. XD But anyways, don't be like me, don't joke about it. "Do as I say, not as I do."
My science teacher showed us a website that contains a world clock. You can see births, deaths, illness, crimes, and whatnot. A bit morbid, I guess, watching as the number of deaths go up (there are really a lot of people who die of respiratory infections!) but it's kind of fascinating too. Here's the url:
