KINETIC DISEASES 241 



shown by the fact that diabetes is aggravated by the 

 conditions which increase psychic strain, and lessened 

 by conditions which obviate psychic strain. The 

 identification of the common causes of diabetes with 

 the common causes of Graves' disease may explain why 

 in the words of a certain phrase maker, "when stocks 

 go down in New York, diabetes goes up " ; why diabetes 

 is more commonly found in large cities, among indi- 

 viduals and races who are constantly under a strain of 

 business perplexities, and who are constantly within 

 sight and hearing of thousands of irritating and harass- 

 ing episodes ; and why it is rare in localities where 

 leisurely and quiet ways of life prevail. In the fact 

 that here, again, the emotional trade-driven Jew is a 

 frequent sufferer, we have pertinent matter for con- 

 sideration. 



Since diabetes not only numbers among its common 

 causes the common causes of other kinetic diseases, 

 but as in the case of Graves' disease, arteriosclerosis, 

 neurasthenia, etc., is improved by rest, diversion and 

 dietetic control, one might expect that as the depres- 

 sion of the activity of one or more of the kinetic organs 

 has proved beneficial in other kinetic diseases, so surgi- 

 cal measures might be of avail in the treatment of 

 diabetes also.
