Your heart sits in the middle of your chest and pumps blood from about 4 weeks after conception until the day that you die. It never stops, and over your lifetime it will pump ~175 million liters of blood. To visualize that, imagine the amount of water that falls over Niagara falls in a few minutes. Remarkable! This little pump is the size of your clenched fist and in an adult can weigh about 300 grams.

The art of this period is familiar, since the world of the Realists, Impressionists and Post-Impressionists is much like our own. More and more people lived in cities and worked in factories or shops for wages. Scientific and technological advances increased dramatically during this period and although there was dislocation and privation, standards of living increased sharply. In essence, modern mass culture was born. Artists responded sometimes by embracing these radical changes, and at other times by resisting them. Key here is understanding the authority of the various art academies in Europe, which controlled matters related to taste and art, and which were, to some extent, always connected to the government. A small number of artists rebelled against the strictures of the academy, and against the demand for art to tell clear stories for a middle class audience, and formed what we know as the
