With all the present talk about our health care crisis, it is worth asking how we got into it. The culprit is history, not conspiracy. Consider that the latest several hundred years witnessed a huge technology change from the prior several hundred millenia in which we evolved from cave men. Item: Nearly all of the presently treatable medical conditions were unknown when our average life span was about 20 to 35 years. Blame not only ignorance, but the fact that our ancestors died before the symptoms could show up. Item: Before refrigeration, non alcoholic juices did not exist much beyond harvest. Before water treatments, most people of all ages had to drink beer or dilute wine to prevent ghastly diseases, such as cholera, dysentery, typhoid fever. Now, heavy use of alcoholic beverages is known to damage heart, liver, brain, and to help cause Alzheimer's. By the way, tea is also a good prevention for water borne diseases. Item: Before gas and electric motors, good "health foods" included fatty sausages. Fat helped to preserve foods, allowed compact transport of a day's calories, and let us stay alive without spending all day grazing, the way cows do.
