What is the right way to hang the toilet paper in the bathroom: Over or under? How does it impact hygiene, and what should be done

The original inventor of toilet paper suggests that the over position is the optimal way to hang it. This approach not only enhances usability but also promotes hygiene, as the loose end can be easily accessed and torn with a single hand. Additionally, this method minimizes hand contact with both the wall and the holder, contributing to a cleaner bathroom space.
