"Experience has taught me to believe that, these human beans are the most insidious enemies man, with a tendency to corpulence in advanced life, can possess, though eminently friendly to youth"

This quote by William Banting recommends that he has actually had negative experiences with people in his life. He thinks that people can be the most unsafe adversaries, and that they become more harmful as they age. He also indicates that they are friendly to young people, but that this friendliness is not genuine. Banting's quote indicates that individuals can be manipulative and untrustworthy, which they can be hazardous also when they appear to be pleasant. He also suggests that people have a tendency to end up being a lot more overweight as they age, which can be an indication of their untrustworthiness. On the whole, Banting's quote implies that people can be hazardous as well as unreliable, and that it is very important to be cautious of them.
