In my mind its absolutely painless. Even if it is painful, people wont have to endure it for long lol. Tell me, does a thermometer tell you how hot it is if you destroy the thermometer?
you do have to be very brave to shoot yourself with a gun.
I agree that shooting yourself with a gun is painless.one moment you are alive and aware the next is like you never existed.
the fastest nerve impulses in humans travel at 120 meters per second.
but bullets travel faster . but imo it's better to use the highest velocity you can get.
i would be using a rifle bullet that travels 2600 feet per second or 792 meters per second.
the nerve impulse has to reach the brain then the brain has to become aware of that pain which takes more time.
the brain is destroyed knocked unconcsious as fast as this gel expands :
hitting the skull (not the face or jaw) with a high velocity round. The round will impart its energy as a shock wave through the brain matter that will essentially destroy it, as the brain has the consistency of a blancmange (jelly and custard).
The bullet strike will be painless because the speed of the destruction of the brain matter is faster than the body can transmit the pain signal so you wont feel the first strike to the flesh of your head as the brain behind it gets destroyed before the pain signal gets there.
In essence one moment you are alive and aware the next is like you never existed.
