Colloidal Silver along with hemp oil are on my list for the next detox supplements I'm getting.
Also hygiene is certainly good but our ancestors never washed their hands or anything and we evolved from their strong immune system developed from that.
I am not saying don't wash hands after using the restroom, especially if in food service to avoid contaminating yourself or others, but I think once in awhile skipping a shower or not washing hands is not as bad as was once thought.
This is of course after strengthening ones immune system with detox supplements like Iodine, silver, and the many others out there that have been used for many years by our ancestors.
