Why is it, that when you hit/smash your finger your first reaction is to put it in your mouth?

It is an impulsive reaction to apply pressure. Whether it is by squeezing your finger with your other hand to easy the nerve endings or to suck on it to ease the pain. I have never seen anyone not smash their fingers or toes and not want to apply pressure to the area.

There are various reasons.   There is the force of habit as mention aboved.  Also, sometimes a player will like to take it out to briefly say something to an opponent or player where there is no obstruction in their speech.  Some players have too much accumulation of saliva and chose to spit as a habit.   Rarely, players also get hit so hard that their mouthpieces are displaced where they have to re-adjust it for comfort.   But the habit thing is probably the most common reason

when i was like 8, we did it all the time. like when you swore to do something. we would both spit in our palms and shake on it. pretty gross thinking back on it.

Because , you know how ur fingers/object (u r going to tickle with) will move in the next instant, which makes the brain & sense orgrans ready to accept it.

If you haven't broken that habit, it would occur mostly when you're nervous and sometimes stress. But it can also occur as an automatic random impulse, whether you're bored or waiting for something (or both). It's the exact same thing as unconciously fidgeting your fingers and, to most girls who have/had braces, puffing up your cheeks.\n\nIt's simply a brain impulse while it's busy thinking of other stuff and ignores all other habitory, well, habits.

Sounds like more than a single punch.  Taste and  sensations about the face come from small cranial nerves which may have been jarred or damaged.  A broken bone is not what you should be concerned about.  You need to see a doctor.

your brain knows it is coming.  it is taking in the sensory information from your hands and the spot you are touching simultaneously, \n\neven when you know where someone else is going to tickle you, you dont know the exact movement of their hands,  (or tongues   ; p    )

Newton's third law: The rate of change of momentum of a body is equal to the resultant force acting on the body and is in the same direction. (from wiki) Fist slamming into victim = large short-lived force, producing a nearly instantaneous momentum change.  Note this is a passive reaction, not a response initiated by the victim.  I'm sure that was what the question was about (heh).

Sometimes your body will react to metal.  Like me...Sometimes my fingers turn green from my rings.  Certain food you eat makes you react to metal differently.

I broke my pinky finger a few years back.  My finger is crooked now, sort of like a bump on top.  Goes with breaking bones, I guess.

It is the child equivalent of get stuffed. If someone pokes there tongue they are basically disrespecting you. Usually a quick slap under the jaw will end that habit.

What the hell's wrong with you.  I looked up your sign-in name, and all 5 of your questions were about breaking your own finger.  It's probably for workman's comp.  \nGo see a doctor.

First impressions are very important.  It has been proven that an opinion about someone can be formed before a 10 word conversation has been had.  And yes, Psycho...  You made a GREAT one...  :)

There are a few explanations. The first for mainly the cracking bones would be the positive feeling one mentally and physically perceives from cracking bones (technically not actually the bones). Because they associate the action with a positive feeling they do it more often.\n\nAnother comes from the stress release. In psychology there's a term called "Sublimation" in which someone will place their agression and stress into unrelated activities. This is an example in which someone might be stressed so they bite their nails or crack their fingers because they find this to be a pleasuring release of tension through the cracking sound or the light biting of the nail and removing it. \n\nAs long as people develop posotive associations with actions they'll continue to do it. At first the discovery is probably accidental but eventually a habit forms (the body seeks positive feelings and stress release).\n\nHope that helps

I'd imagine it would have something to do with the stages of shock. Depending on the situation and your state of being (are you in danger of bodily harm or not) you would go into a state of disbelief or denial. Example: What news you had received "just CAN'T be true!"
