I'm also 55 and have never even thought about parasites living in my body until I started reading about it all over this forum. I choose to not worry about parasites because if such a thing exists, like you said it would be cleared up with a fast to completion. I think people who come up the the remedies to such as parasites put fear into people so they can sell a product, when really our bodies were designed to heal themselves if given the chance.
Thank you Chris, you are so kind to answer all the questions we throw at you. I wish you well.
