There are several ways from which we can protect ourselves from quackery. First of all let us define the word quackery, it's an untrained person who pretends to be a physician and dispenses medical advice and treatment. We should never listen to their advices. Secondly, let us see the ways that we can protect ourselves and stay away from these advises. We should never listen to advices from unskilled people who pretend to know what they're saying. Thirdly, we should ignore all the attractive advertisements that we see in the daily newspapers. Some of them might be faulty but still some might be right, just incase we should ignore all of them. Finally, to prevent ourselves from serious injuries and sickness we must listen to the advise of a skilled person if we have a certain problem.
