Prevalence of quackery in our society is as old as the society itself. In olden days, folks used to blindly believe the good-at-words, weirdly dressed man sitting at the corner of the road, claiming to have remedies for all the ailments that ever saw the light of the day.
Times have changed. So has the educational levels and scientific awareness. But sadly, quackery still prevails in many forms.
The interesting part is, now the “up-market” quacks are making full use of the modern technology in selling and promoting their stuff through media like Internet and Television and other hi-tech areas.
