Now I've heard everything... Using a 40 day fast to cure acne. I suspect what happens during a forty day fast is that a person loses brain cells. That is why they have the feeling that they feel better. The remaining brain cells are using the dead brain cells as food to survive. Each time they do a 40 day fast they lose more and more brain cells. It explains why some people are so stupid. I'm still trying to figure out what is causing the original stupidity to want to fast for 40 days. I believe it may be that somewhere they inhaled carbon monoxide for a significant period of time. That would explain the original desire to harm themselves. Just a suggestion to all those that believe fasting is good for you...DON'T BELIEVE EVERYTHING YOU READ ON THE INTERNET.
