Whether you like it or not, on this day, in your birth year, the world changed. I am sure you have heard of the butterfly effect. Everything you do has almost infinite positive and negative consequences. Some actions have more positive influences than others. Due to your day of birth, more diversity crept into this world. So, if for nothing else, let us celebrate the diversity that you are responsible for. That is a very good reason to eat cake :D Happy day of increasing the human population :D
