Thanks Spud - that is reassuring - I hope you are right! I do believe that making an unfavorable envirement and forcusing on good overall health is best. (I do this, much more than anyone I personally know) I just know how easy it is to catch parasites, and don't want to have them!
I've read that people that perform colonics see tons of intestional parasites... My sister had many tapeworms, not just one, and also several other varieties.
