You have to come down here and teach economics sir (haha). I have sat in economics class struggling to understand this stuff and it has always been explained in ways that makes it sound like speaking Japanese to an English child. Today you did it in an interesting way. It only makes sense that elasticity and inelasticity depends of the amount of options available. More options therefore mean for elasticity. I have now captured this concept. Thanks @spectrumecons for this article.....
