Here is the crazy (another theory):
Roussau's genetic mirror theory says that everyone in the world has an exact twin somewhere, however according to the theory you never encounter this person, by laws of probablitly and other natuaral occuring phemnomen. Its the theory that was devised by a French Mathematician named Marseille Roussau in the year 1988. He used a series of numbers to explain his theory. Now I know you're not going to believe this but here goes. 4 8 15 16 23 42 The 4 stands for 4 degrees of separation (not 6 or 7 as commonly stated.) Roussau believed that everyone in the world was connected by four different people. So in theory could meet yourself by using four different people connected to you. Example: Your brother's, boss's, neighbor nephew, knows your mirror. The 8 stands for the eight continent, or the only place in the world where you could meet your mirror. He calculated it to be somewhere in the south pacific. Now we know its not actually as large as the other contintents but its used figurtively because everyone in all 7 continents could meet there mirror on the 8th universal continent. The 15 stands for the chances of you acually meeting yourself on this place, as in 15 out of 4,815,162,342. Look at the second set "815." Ring any bells? Interesting huh? The 16 stands for the maximum amount of people that could encounter thier twin all at the same time. Think about the number of main characters. The 23 is the number of years apart your twin and yourself are. You are not the same age as your twin. By chance and probablity it takes 23 years exactly for the same genes that made you to be connected again to form another you. The 42 stands for the maximimum number of years your twin and yourself can be alive at the same time. However people do die at diffferent times so thats why everyone isn't dead at 75. For example my twin was born on Sept. 6 2003 b/c i was born on Spet. 6 1980. Now that doesn't mean i will die in the year 2045, I could, but its not set in stone. My twin could die when he is 16, and then the whole thing starts over.
