I have been looking over some vintage advertisements which seem ridiculous in contrast to present day knowledge. Fifty years ago, however, many people didn't think to question this marketing. So fifty years from now, what will we think about the commercials which are bombarding us today? You can't trust anyone who is trying to sell you something, especially with your health. Read your labels. Study the ingredients. Do research on the hazards and benefits. And trust yourself to make the best decisions for your own well-being. No one else is going to do it for you.
