Sometime in history in some part of the world a wise man had a theory on life:

When a person is born he/she starts a race and runs at a constant speed down a track. Not long after the race has started, an archer shows up at the starting line and taking aim for directly the back of person's neck, he fires an arrow that travels faster than the person running. Now the person alreasy has a head start but no matter what, he/she cant avoid the sharp head of the arrow that is getting closer and closer; he/she cant run any faster, cant get off the track, cant ask for help, cant stop and most definetley cant turn around and run towards the arrow. (Very stupid thing to want to do in that situation mind you but whats important is the point being proven) As the moments pass the arrow gets closer and while the person continues to run, he/she can only stay ahead for so long before the arrow catches up and the race is finished.

-This scenario might not be possible with the laws of physics in mind but what matters is that it explains very accuratley what each human faces, and also makes many valuable points about all aspects of life that we should all keep in mind as we run our race. Im not gonna try and interpret for everyone what this theory means exaclty, instead I leave that to you. Afterall, I have my own race to worry about!
