once i wrote the following. i thought it was intelligently put.
You are different, and so is everyone else. in fact, there is a dismal 1 in 70 trillion chance that any parents would be able to recreate an identical offspring. in short: have sex 70 trillion times and only 1 will be the same as the one you had before! by the way, 1 trillion is the number of 1 dollar bills (american) it would take to fill 1 million olympic sized swimming pools. 1 million is the number of single strands of hair it would take to pile as high as a 7 story building. essentially, 70 trillion is a number impossible imagine.
