I am not a skeptic of the MGSL. As I said in the beginning, I must believe those who say it works because I have not tried it. I may buy one & see what it does for me. I was not attempting to discredit the MGSL or TR Graham; if someone has taken it that way, I apologize. Also, just because I do not agree with someone's explanation of the mechanics does not mean that I do not understand the explanation.
