For the purpose of reaching these suburbs there was involved the circulatory or Thoracic system, and this gave rise, as we have seen in the previous chapter, to the Thoracic type. Movement and Development ¶ As time went on movement became necessary, full development not being possible to any static organism. To meet this need muscles were evolved, and organic life began to move. It was only a wiggle at first, but that wiggle has grown till today it includes every kind of labor, globe trotting and immigration. The Muscular is fitted with the best traveling equipment of any type and invariably lives a life whose main reactions express these things. The Immigrant Muscular ¶ No matter what his work or play the Muscular will make more moves during the course of a day than other types. He loves action because his muscles, being over-equipped for it, keep urging him from within to do things. As a result this type makes up most of the immigrants of the world. Italians, Poles, Greeks, Russians, Germans and Jews are largely of this type and these are the races furnishing the largest number of foreigners in America. Inertness Irks Him ¶ Shut up a Muscular and you destroy him. His big muscle system cries out for something to do. He becomes restless, nervous and ill when confined or compelled to be idle. The Alimentive loves an easy time but the Muscular dislikes ease except when exhausted. Even then it is almost impossible to stop him. Must Be Doing Something ¶ "I can't bear to be doing nothing!" you often hear people say. Such a person always has plenty of muscle. Musculars want to feel that they are not wasting time. They must be "up and doing," accomplishing something. If there is nothing near them that needs doing they are sure to go and find something. The Born Worker ¶ Work is second nature to this type. He really prefers it. Everyone likes some kind of work when in the mood if it serves a purpose or an ideal. But the Muscular likes work for its own sake--or rather for the activity's sake. Work palls on the Alimentive and monotony on the Thoracic, but leisure is what palls on the Muscular. He may have worked ten years without a vacation and he may imagine he wants a long one, but by the morning of the third day you will notice he has found a piece of work for himself. It may be nothing more than hanging the screen door, chopping the wood or dusting the furniture, but it will furnish him with some kind of activity. Because he enjoys action for its own sake and because work is only applied action, this type makes the best worker. He can be trusted to work harder than any other type. Require Less Watching ¶ It is no accident that the three-hundred-men gangs of foreign workmen who dig ditches, tunnels and tubes, construct buildings, railroads and cities work with fewer foremen and supervisors than are ordinarily required to keep much smaller forces of other employees at their posts.
