I think that if you're really interested in how the places "work," or don't, you should take a look at some of the research that's been done by the National Institute of Health (NIH) under the guidance of the Surgeon General.
The studies are definitive. Of course, there are always exceptions to the rules, and if you feel it worked for you, whether it did or not, the important thing is that you are healthy today.
As long as you weren't abused, I could not care any less how you got that way (healthy), but thank God you did.
To me what matters most is that you are healthy and happy and I'm happy for you that you are...
