MAN'S DEPENDENCE 



There is much that each one of us can do to keep his 

 body jit for work and play and for the enjoyment of life, 

 and it is important for us to get certain habits and atti^ 

 tudes that will preserve the health of the body. But be- 

 yond a certain point we cannot keep healthy alone. There 

 are other people and other species of living things to con- 

 sider. We depend upon others both for our material needs 

 and for our happiness and comfort. A large part certainly 

 of what is called spiritual welfare means healthy relations 

 to other people. But the physical welfare of the body is 

 constantly influenced by the doings of other human beings 

 and other organisms, plants as well as animals. We must 

 consider how we may control this outside world for 

 human health.
