I want to believe me neither but lately I've researched some personal medical issues and the amount of well written absolutely not-scientific (while citing lot's of studies) blog posts / sites that sell you something and make you believe you have an non-existing disease that's easy to self diagnose (https://en.wikipedia.org/wiki/Adrenal_fatigue) is pretty high for any medical topic.

If you are desperate and someone is able to convince you that he can solve your problems for only 20-50$ no questions asked, next day in delivered to your home wouldn't you click if you had the money?
