newton's first law is the law describing inertia--pretty much everything you can see obeys this law--that it does not budge unless acted upon by an external force. and much of science has been devoted to predicting the behaviours of objects untouched by external forces...ballistics, planetary motion, and other parts of newtonian science. then people figured out how to analyse external forces too, and so you have mechanical engineering.
but what separates life from dead objects, is the ability to cause an external force upon itself--external force derived internally. so while a falling rock always falls by gravity, a bird can choose to change its trajectory at any time. while a bullet leaving a gun can only fly in a calculable parabola, a human cannonball can change his/her trajectory at any time. while a gear can only spin at a calculable rate, a deskjob employee can get out of his cubicle at any time.
for living objects, all paths are bendable. the necessary existence of a finish line is not the same as its finalisation in position of time or space. of course there is a second chance. there are third and fourths and fifths, assuming you want to count them in integer values. youre still alive...
go bend your trajectory
