Archery players press their lips and nose with the bowstring during the ‘anchoring’ stage, where they pull and secure the bowstring.
This is why the marks of a pressed bowstring remain on the lips of archers.
The lips are important because when archers aim, they always fix the bowstring on the same part of the lips.
Even if the location changes by just 1 mm, the arrow can deviate significantly from the target.
This is because the area around the lips is very sensitive, making it suitable as a reference point for accurate aiming.
The nerve at the tip of the lip makes this possible.
