<p>Aimed at the general public, this film explains arteriosclerosis and atherosclerosis and how it affects health. Blood in circulation is seen; a comparison is made with blood and traffic congestion. The film explains in readily accessible ways how the hardening of the arteries adversely affect health. An experiment with two beakers demonstrates shows this. How clots form are also described. Diagrams describe how a clot can lead to a heart attack. Researchers realised that atherosclerosis was not just a disease of old age; they looked at cholesterol as the culprit. Fats are looked at in the laboratory; in Europe a study between 1938 and 1948 indicated that diet was involved. 'Harmless molecules of fat' are injected into the body of a man in a research setting so that Geiger counters can identify where the molecules reside ('using atomic energy for medical progress'). In the laboratory, medical research continues.</p>
