Cause or coincidence: Now you know what a "testimonial" is. A testimonial is something you say happened to you, such as "I stopped eating plums, and my skin is much smoother". It often is a coincidence, the things that are happening, and are not "cause and effect". That means "not eating plums" does not cause skin changes, but both things occurred around the same time. Coincidences can fool you, if you let them.

EXACTLY. Biotin is strictly for suckers. It is a waste of money.
