im a diabetic u shouldn't have to force it till it hurts your finger if blood isn't comin out enough to test then sett the pricker to a higher needle setting but yer it shouldn't hurt hope this helped
i know the air force uses urine and blood, but not hair; not sure about the other branches
There is no special force causing this. When you put your finger in a socket the large amount of electricity coursing through your body causes instant and extreme muscle contraction. It is this that propels you away from the socket. This is also why, when testing an electric fence, you should always do so with the back of your hand to prevent your hand clamping over the live wire.
The action is the finger pushing the nose. The reaction is the nose pushing back on the finger.
Cohesion.

the air friction
the force with which what the contract causes blood pressure
A force which (hampers or hinders) retards motion is a retarding force. Say for example if a ball is in motion and you sligtly touch it with a finger then it slows down before coming to a halt.So, you or to be more precise force excerted by your finger is a retarding force .
this is blood pressure

compressive force
