A theory of boredom

Have been operating out of home for a few days. On occasions it gets so so so boring that mind stops working and sleeping becomes tough too. So, with no options left, I have to endure the 'boredom' sensations.

However, I have been wondering how could 'boredom' have evolved. Here's my venture.

It seems to me that most of the time, since our evolution as 'humans', we would have spent doing nothing but either sleeping or staying 'alert'. That's right, staying 'alert'. Without concrete or solid protective structures around, that would have been the only option. To survive, staying alert the entire day was an imperative. And that was the occupation. And alertness induced action.
  

So, any task or occupation that doesn't match the evolved sense of alertness among humans is bound to seed 'boredom'. Over a period of time, as this seed of 'boredom' grows and as our own acceptance of 'boredom' grows, we lose what nature gave us - alertness and the propensity to act.

That's also one reason why, in spite of seemingly high degree of risk, entrepreneurship is alluring. It heightens our sense of alertness to a great extent. We have to be on our toes and wits :) to 'survive'. Alertness is the herbicide which checks the spread of boredom in our lives. Indeed, you are responsible for putting yourself in such situations where you have to be alert or you will be 'die of boredom'.
