Theory

I have a theory. There is nothing like fluke, everything just fits into the grand plan of things. Just before we are born, up in heaven each of us is sent to a kind of big department store, much like the time before school reopens for another glorious year, where, you have to buy books, uniforms, shoes, etc...

In the heavenly department store you decide the happiness, sorrow, challenges, experiences, etc, down to the smallest task you will perform whilst on earth. While you live your life on earth back in heaven they keep track of the smallest detail of the number of tasks you perform in your day to day life. Yeah they have filing cabinets filled choc-a-bloc with details of all the good/Bad deeds you did.

For e.g.: the smallest thing like the number of plates you wash, the number of clothes you wash, the number of times you run errands for others, the numbers of times you cheated, number of times you hurt someone etc, this is all match against the number you picked before being born.

Then based on your performance you are progressed to the next level in life. Still working on this theory... will come back and post some more :)
