Do you remember when you were a child, every evening your parents would say: “Don’t forget to brush your teeth before you go to bed!” Or the slogan of oral hygiene professionals, “Brush your teeth twice a day; see your dentist twice a year!”
Both slogans are still current today, as is the trusty toothbrush needed to execute the admonitions. The fact is, the humble toothbrush is a virtually indispensable feature of our everyday life; however, the toothbrush isn’t really all that humble. The designs and materials used in its various manifestations are the result of decades of careful scientific investigations. And development continues apace. Today if we so fancy, we can even choose computerized versions of the toothbrush that link to the internet to provide aspects of oral hygiene previously never even imagined.
Given its ubiquity, hygiene, and social importance, the toothbrush
unquestionably deserves a place of honor on the list of what I like to call
“extraordinary ordinary things.”
“Say, what time is it?” If you are like most people, you will take a glance at your wristwatch and quickly give the answer.
Today, the wristwatch is almost as much a part of us as our skin; however, just over a century ago, this wasn’t the case. In earlier agricultural populations, few people were concerned about the exact time because they didn’t need to be. Concern about approximate, if not exact time, was essentially in the domain of kings and emperors, servants of such royal personages, and the aristocracy, who represented only a miniscule fraction of the population. It is really only since the dawn of the Industrial Revolution in the mid-18th century that knowing the exact time has become a significant concern to a significant portion of the population.
Rubber is one of the most common substances in the modern world, and
certainly one of the most undervalued. If you ask someone to quickly name a
product made of rubber, you are likely to get a reply such as a pencil eraser,
rubber band (“elastic band” in Britain), rubber bathmat, rubber stamp, rubber
toys, rubber balloons, etc. On further reflection, the person might add objects
such as garden hoses, aprons, surfing wet suits, gloves, etc.
By themselves, none of these things have radically changed our social
environment and how we go about our lives in it. However, take away any one of
them and we are likely to feel a significant difference. This is why I believe
rubber justifiably deserves to hold a place in the list of what I like to call
“extraordinary ordinary things.”
The first part of this
two-part blog, published last month, explored the fundamental ideas of money.
Here are some key things to bear in mind as we continue our exploration of this
endlessly fascinating subject.
- Money is a universal
token (metal coins and paper bills) having a value that is expected, but not guaranteed, to be stable over time and is trusted by the people. This trust is usually established by a national government issuing and standing behind its currency (dollars, euros, francs, kroners, pounds, pesos, etc.).
- Money is a great
facilitator of exchange transactions (buying and selling), the core of
- Money has no intrinsic
value. Even when money is equated with silver or gold, the value of money can
fluctuate with the prices of these metals.
- Money must move
quickly and seamlessly from one place to another in today’s largely integrated
worldwide society, which was not previously the case in local, largely isolated
In short, to a large extent, the
legitimacy and value of money is whatever a national government says it is.
