Those who cannot remember the past are doomed to repeat it - George Santayana.
How many times have you heard that phrase? I bet, many. Mostly by people with a "know-it-all" complex, who with a grin on their faces go around repeating " I told you so" to anybody they can find. I only wish they would walk the talk.
In the age of information, I find it ironic that we still make pretty basic mistakes. It is not surprising though as in school we were forced to learn pointless dates for events that were overall inconsequential to our childhood when naturally we were more interested in having a good time with our friends.
