life.

first, you are born. you are catered for and nourished by your parent(s), or, left to fend and mature both physicaly and mentally for yourself. either way, you develop. you will learn how to acquire food for yourself, and perhaps hygeinic habits to prevent disease and threats to your life. you will learn how to communicate amongst your own, or perhaps, learn no skills or that type, either through developmental neglect, or because they are unrequired. ultimately and eventually, you will be able to rely on no one but yourself. soon, you will grow old, and since you will not be able to function for yourself, you will die, having served no purpose through your entire life, other than to, perhaps, spawn one of your own and force this cycle upon another.

of course, for the human race, a lot of this is different. figure the differences for yourself.
