Is it art?

The answer to the question of "Is X art?" has been a defining point for societies across the span of millennia. The concept of art in more recent times (the late 20th century and on) has seen the array of topics considered to be art explode, why is this though? The answer is that in the later half of the 20th century the general consensus on what art was evolved to any form of self expression, no matter how ordinary or extraordinary a piece of work was it was all considered art. That list of people whose opinion that any form of self expression is considered art can also be extended to include my name, however with one abridgment, the addition of the phrase "within reason" at the end there.
