Answer 6

In terms of bio, there are special nerves that detect changes in texture, pressure, temp, etc

if the pressure gets too intense, then the nerves send signals to the brain to indicate there is pain or discomfort

I'm not a bio expert, so you're better off asking for a second opinion

"For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object."
