Well said and the kind of wisdom that endures throughout all time. Feldgling your post is a treasure!
My belief is that Life is a cycle. It's about soul growth...learning, forgetting and relearning once more. This planet is where we come to experience for it is through experience that we gain knowledge. It is about Karma too. In the Bible it says that the sins (parasites?) of the fathers will be visited upon the sons.
We come here to learn about trust. Trusting in the Universe.
As for any posters concerned about their children there are other ways to deworm without the use of strong herbs (sorry Humaworm) but this does not in any way detract from the HW products since I am a customer myself!
I am of the opinion that it is a good idea to change products and methods with parasite elimination so as not to give them a foothold. Change tactics so to speak.
