A lot of mouth bacteria lives on your tongue. Any dentist will tell you that cleaning your tongue is an important part of oral hygiene, even though it’s often overlooked. Doing it really helps with keeping bad breath under control and generally healthier teeth.

I have a hard time imagining how any other business model for distributing video content would look like, but then again I don’t have a very entrepreneurial mind.
