Rule #5. Take a proper seat.
For a very long time in human history, there were no actual toilets. The toilets that we are familiar with and use today were very recently created. But the position we adopt when using one of these toilets is not normal. Constipation and hemorrhoids can result from the 90° posture (on the left), which also creates stress and strain. Additionally, it is normal for everything to proceed naturally at a 35° angle (to the right). Therefore, it is preferable to sit in the 35° position to prevent any injuries because we typically have to rush when using public restrooms. You should keep in mind, though, that not all public restrooms permit users to stand on seats. So, to avoid the bacteria, just don't touch the seat if you're in a restroom like that.
