How come karate masters can break bricks but cannot break humans the same way?

Sparring is a friendly competition. Place someone's arm across a couple of blocks and let them hit it the same way they break bricks and that bone is gone.

Karate tournaments lol. it's more a sport. they wear protective gears and it's a point scoring match. where to win is by "getting points" not knocking out your opponents unconscious. THAT'S WHY IN SOME SO CALLED WORLD MARTIAL ARTS COMPETITIONS(ANY STYLE YOU CHOOSE), KARATE ALWAYS GETS GOOD RESULTS cus those match are for point scoring. though if the "strict restrictions" on these point score match were lifted, i would see other martial arts getting more placements. But a karate master can sure break someone's shin just like how they break a baseball bat with their kicks.

it's because the bricks are oftenly brittle than the human body that is flexible

bricks are self made to be weak. too many people believe that they could break heads using this mystic force, but you know... bricks stay there waiting for the minute of focus. which is rubbish anyway, because bricks do not make for power. people do not stand there waiting for the karate brick fighter to charge up his focus. it is like a circus feat. no more. how many times have you been in a fight and used it on the street? none. why? not because of some creed that forbids it, because I would use it to smash some muggers @ss, but because it doesnt work like that. if you havent used it against a human, you are full of sh!t. and just a punch from someone who doesnt practice brick breaking can break bones like ribs, jaws, cheek bones. and chops can crack collar bones. I have broken ribs kneeing to chests, and I didnt need brick training. you dont need to have the force to do it. tournament trophy's dont mean you can fight, all it says is you can out combo your own style. brick breaking shouldnt be confused with martial strategy and power.

Cause if you have ever seen a brick breaking competition it takes the guy like a minute to set up for the strike, who is gonna stand perfectly still during a fight. Plus its so dumb why would you hit bricks and wood, it makes no sense. Have you ever seen a real fighter like those in MMA ever practice breaking bricks? NO, cause its pointless.

It has to do with that whole fleshy thing we call a body surrounding muscles....

I think you should double check your resources because there has been more then one death in the ring. It is something not is not much talked about do to respect. (77)

iv'e never broken a brick,iv'e never been attacked by one though.do you think karate people just stand around waiting for a brick or a board to attack them?if people got seriously hurt in a karate tournament there wouldn't be many tournaments,now would there? I dont know what toilet wall you got your knowledge of karate from but nearly all karateka would know how to break bones. people buy guns to target shoot,ive never seen any of them shooting people.so apparently a gun can't injure,maim or kill a person?

it is because bricks are harder than humans. the point of impact in a brick will absorb all the energy of the hit causing it to be the breaking point. humans on the other hand, can (and will) have a reaction to the blow wherein the point of impact will absorb only a part of the power of the hit and will distribute it to the surrounding of the point of impact which will not cause a human being to break apart like a brick would. and also, bricks contains very minute or absolutely no water at all which makes it brittle unlike us humans.
