Caffeine

Caffeine have beneficial effects on the body because it enable us to stay awake. An example of this is me. Late in the night maybe around 10pm, as I was rushing my homework, I would have a cup of coffee so that I would be awake. Although I feel that it does not do much, I would feel awake as I felt that the coffee would have kept me awake. Hence I would be awake and continue to concentrate on my homework. Thus this shows that caffeine have beneficial effects on the body as it enable us to stay awake.
