With all due respect to DB, Lou Gehrig's disease is a genetic disease.
I'm not trying to be argumentative in any way, but I don't see a connection between the two. Herbs don't cause it, not can they cure it. The doses available in HW couldn't hasten its onset. If you're going to get it, you're going to get it.
DB, if you're reading this, truly, my heart goes out to you. I'm not trying to argue about your beliefs in this matter.
