No. Even if you're so stupid that you have no internal defense mechanism to inhibit your own punch, you can't generate enough force with just your arm to cause a concussion.
If you're still very eager to render yourself unconscious, may I suggest a noose?
Although it would take a lot of force someone who gets punched in temple hard enough would die that is where a lot of your important nerves are located. I highly suggest if you are asking because you are intending on killing yourself you talk to someone before making you make a make a permant solution to a temporary problem.
i dont think so
no and anyway that's just stupid
Sure. It hurts, though. Alot trust me i know
If the strike is issued with enough force, the victim will go into shock.
Yourself
If I punch someone, they will deform where they are punched. The punch is a transfer of energy - force.
Depends on how much force is placed into a punch.
There is no single measure of force for a boxer's punch.
punch yourself in the face === ===
express yourself
yes you should right in the temple as hard as you can
You can mark or slightly dent steel with a brass punch, but the steel is always going to win.
breath in then punch yourself in the belly
