Have you ever noticed how many products that we buy everyday is already sliced into parts. Have you ever wondered what is the goal of making parts out of something. For example, why do we get many smaller cookies instead of one very big? What is the point of it? Well first of all dividing something into parts guaranty that it is easier to find the right dose of the product. That is very important in case of pills for example. If we take a medicine it is easier to take the appropriate amount if it is already in form of pills instead of powder for example. Another advantage of things being in parts is the fact we dont have to eat everything at once. It occurs that even more abstract things can be divided. Let us take Theory driving test for example. Not long ago there was a proposal to divide it into separate parts each concerning different aspect of driving. That would allow to see the skills of people taking the theory driving test much easier. Still, the idea wasnt introduced into life. How do you think, would that be a good idea? Because I cant find any reason for dividing this course into various parts. It doesnt convince me. Maybe it is just another idea without sense whatsoever.
