People like to believe in that stuff because it's an easy solution and it also thwarts facing real issues if there are any. Really it is as simple as that...take a pill and voila, your hopes and dreams all come true. Never mind that say losing weight for example involves a lot of blood, sweat, and tears...even more so if you actually want to get your body into toned shape and not just skinny and droopy. The hardest and best thing you can ever realize in some things is that sometimes the harder way has more rewards. IE with weight loss, the loss is only the first of the rewards...improved health, better emotional health and balance, and more energy are also rewards that don't get nearly their due and once you lose weight they become much more important then the weight loss anyway. I continue to workout because it makes me feel my best and keeps my moods, especially during a difficult time, balanced. It keeps me more optimistic and gives me more endurance to face challenges both physically and mentally.
In regards to my second point, people would rather believe that they can have a simple colon cleanse to beat constant fatigue instead of finding out that perhaps they have a more serious chronic condition. The two kind of go hand in hand--both are easier to deal with both on a physical and mental level then the reality of the changes or diagnosis potentially to be made in the other.
I hope that made sense.
I kinda laugh at the dummies talking about quackery though. Aren't these the same people who send healing white light and burning pine needles wrapped in a bunch to ward off ill health and boost their chakras?
