 PERPETUAL YOUTH. 



The poet informs us that no one ever 

 *~mly longs for death. Tt is life, more 

 life and fuller that we want, -c is 

 true there is an instinctive grasp upon 

 even the, seemingly most undesirable 

 life, but the hold is instinctive rather 

 than reasonable. The love of youth, 

 however, is dictated by reason. Its de- 

 sirability is seen by all. My friend 

 once said, "I would far rather die than 

 be old." 



Scientists have been trying for ages 

 to discover the secret of perpetual 

 youth. They have arrived at a plausi- 

 ble theory and it remains with 1 the 

 present generation to test its practical 

 merits. 



Youth is the period of construction. 

 The child eats to live and , to grow. Af- 

 ter maturity he should eat only to live 

 and, accordlngi to modern theory, if 

 this were done there would be no pe- 



riod of old age. In youth there is a 

 natural elasticity of the walls of the 

 arteries which assists circulation. So 

 long as nutrition .supplies only Waste 

 the elasticity continues but as soon as 

 nutrition becomes more abundant than 

 activities require the surplus is depo - 

 ited causing a hardening of the walls 

 of the arteries. This hardening inter- 

 fere^ with the perfection of the whole 

 circulation and thus introduces the 

 commencement of the period known as 

 old age. Accordingly old age could be 

 prevented by supplying less nutrition 

 of by using the supply more lavishly in 

 larger activities. It is usually recom- 

 mended both to eat less and to exer- 

 cise more. 



As I have already .said it rests with 

 the present generation to test the va'ue 

 of the assertion. And yet we can look 

 about us and see the probability of 

 success. Years ago it was considered 

 that maturity with its burden of work 

 and care required more nutrition than 

 the growing child who is none the less 

 busy because its activity is expended 

 upon what the hard-warking parents 

 call play. still larger supply of nutri- 

 tion was supposed to be required as 

 the weakness of old age approached, 

 s a result we saw commonly a slug- 

 gish, feeble old age at three score 

 years and ten against which we now 

 more frequently find youthful activity 

 and vigor in the eighties. 



The greater youthfulness of the 

 pesent examples of advanced age are 

 due not only to greater activity and a 

 possib'y greater abstemiousness", .but 

 also. to a different frame of mind. In 

 former years old age was , invited by 

 being expected. M'en in their prime re- 

 tired from business and sat down .with 

 open arms to await the advent of the 

 spectre. Mothers resigned their house- 

 hold cares to the daughters and mis- 

 took the consequent'* loss of interest 

 and capability for the approach' of old 

 age. Gradually,, however, a change 

 has come. ■'< Reason points: out the ab- 

 surdity of these, things and the human 

 will has asserted itself and that, , as all 

 'physicians know is a power. An old 

 soldier, wounded and apparently dy- 

 ing, was told by the surgeon that he 

 had but one chance in a hundred to
