Document Summary
Infectious disease has controlled human life since we began farming food 11,000 years ago. Europe began to escape disease in the late 1800s. Other countries began to escape in the 1900s. Population growth, evolution and short term economics are the "future eaters" Organisms that cause severe disease are also known as pathogens. Genetic mutations or environmental stress (diet, uv, etc) cause non-infectious disease e. g. downs syndrome, fragile x, etc. No permanent home, so left feces and parasites behind as they moved. Small family bands, separated from others, so a disease might kill a few, but then die out. Farmers gave it up for hard toil, poor diets, and disease. Life in one place: villages/towns: high densities, sharing food and water, excreta where others might contact it. More grain, less fruit, protein, fats and variety. The industrial revolution reduced the toil, gave more food to all except the poor, but made disease much worse.
