Ignorance and bliss

My life began eight thousand six hundred and twenty nine Earth days ago on a small blue and green planet that is roughly four and a half billion years old.  Earth is elliptically orbiting a relatively small star located in the outskirts of the Milky Way Galaxy.  On the day I took my first breath the star we call our sun appeared to rise in the East, and set in the West.  

Since then I have learned to; drink, eat, walk, talk, run, jump, socialize, learn, play, question, imagine, read, write, add, subtract, use a computer, try avoid being awkward, and write a blog, not necessarily with any expertise, or  in that order.  Assuming that I started with no knowledge at all, a blog entry concerning everything I have learned during my life would be surprisingly large, which might not interest you. 

If infants were not equipped with the ability to learn then we would not last long as a species.  With this in mind, at what point in life is it appropriate to stop this innate process?

By the time we reach our late teenage years I believe young people have most of their prejudices wired into their complex brains, and begin making important life decisions using these sets beliefs.  These biases are probably made up of a vast array of childhood and adolescent experiences, and may or may not be representative of how the world really works.  For instance, a child who was born and raised in Massachusetts might not be cheering for the Vancouver Canucks right now, and this is clearly delusional.

Since being omniscient is not a human quality, there seems to be limits to how much we can actually know.  What we, as individuals, should refrain from doing is substituting our lack of knowledge with preconceived opinions about any unfamiliar noun.  Although some of our beliefs regarding famous people, distant Countries, and Tigers may seem to be justified; sometimes our biases can blind us.  Our ability to learn is innate and it would be unreasonable to believe that there comes a time in life where we ought to stop this blissful process.
