At different times in a man's life his food has different effects on his body. Among children food is quickly changed to the power to run and play games. Most of a young man's food is spent on growing tall；we grow upwards only during the first twenty years of our life, not later. Working men get their strong bodies from their food;and if they work hard, they do not get fat. Office workers eat well and sit
down a lot, and may begin to grow fat when still quite young. Many older people try to work much and walk often.Perhaps the most difficult time is when a man reaches sixty years of age. His body and mind become restful, without much work or interest .That is when food changes quickly to be fat.
