The continuous and free circulation of the blood is absolutely necessary for physical well-being. The circulation can not remain normal unless the heart is in good condition. The results of heart disease are many and serious. At first the symptoms may be SO mild and vague that they are attributed to other factors, but in time the heart condition will be unmistakable. When the circulation of the blood is impeded the body fails to get sufficient oxygen and nourishment. It also fails to rid itself of the harmful waste which is produced every minute Of life. Then physical degeneration soon ensues.
