However, the Cluthe Truss or Cluthe Automatic Massager provides a way. And is the _only_ thing ever invented that can both _hold_ the rupture and give Nature the necessary assistance in the process of _strengthening_ the weak parts. Just _how_ it assists Nature is explained in the next chapter. _+How to Overcome the Weakness Which Causes Rupture+_ A New Way, But Based on a Principle as Old as the Hills-- A Principle Recognized by all Doctors As everybody knows, you can make most any part of the body _strong_ simply by _exercising_ it. Exercise is a wonderful thing. Keep a child cooped up-- give it no place to play-- and it will probably grow up puny and sickly. While a boy on the farm-- with the big out-of-doors for a playground-- is usually a picture of health. Or take a blacksmith. He is constantly _using_ or _exercising_ his _arms_. So you'll find _them_ as hard as nails. While his _legs_-- because he doesn't _use_ them so much-- aren't likely to be nearly so well developed. A man in an office or store usually has soft, flabby, _weak_ muscles. But let that man take up some form of _exercise_, like tennis or base ball, and his muscles will soon be strong. It is a law of Nature that our minds and muscles grow by proper use, building themselves up to meet any demands made on them. That is why, after any sickness which leaves the body _weak_, doctors nearly always tell you to take plenty of _exercise_. Until recent years, the only way to develop strength was by _active_ exercise; movement of the muscles by their own force, as in walking, chopping wood or playing some game. But nowadays there is a _substitute_ for exercise. [Sidenote: Massage Is a Substitute For Exercise] Called _Massage_; a sort of _artificial_ exercise; a way to strengthen muscles _without using_ them. In simple language, massage consists in alternately expanding and contracting the muscles by applying a gentle force _externally_, instead of moving them by voluntary and _internal_ force. Now massage-- like ordinary exercise-- is so _strengthening_ that it will overcome almost any kind of _weakness_. So _invigorating_ and _beneficial_ that many well-known physicians say the day is coming when it will be an almost _universal_ method of _cure_ for every trouble in any way due to weakness. At the Vanderbilt Clinic in New York, many cases of weak _ankles_, weak _backs_, etc., have been cured by massage. Now Rupture, as shown in the last chapter, is _also_ a weakness. But massage, as given at hospitals, can't be used to advantage for rupture. Too _expensive_-- requires an _expert_. And could be given only when you are lying flat on your back in _bed_; therefore couldn't be given very _often_; and it would take years for only _occasional_ massaging to overcome rupture.
